Monarch Pass

April 04, 2026

Our return from Utah took Melissa and I along the southern route through Colorado to avoid having to drive the steep passes of the central Rocky Mountains.  Melissa drove the 13 miles (21 km) of 6% grade on I-17 that drops into the Verde Valley and neither of us were excited about a repeat.  Things began as we took US Highway 50 out of Grand Junction, encountering rolling hills but nothing we could not handle.  Then we saw a sign that said Blue Mesa Summit (elevation 8,704 feet or 2,653 m) was just ahead.  The pass divides the watersheds of Little Cimarron River to the west and Blue Creek to the east.  This stretch is approximately 12 to 15 miles (19 to 24 km) long and has sections with grades of 6 to 10%.  Having ridden Verde Valley the previous week I was prepared for Blue Mesa and drove through without much concern.  I assumed we had made it through the lower Rockies, and I breathed a sigh of relief.  Little did I know looming 50 miles (80 km) ahead was Monarch Pass. 

When I went online, I found Monarch Pass (elevation 11,312 feet / 3,448 m) is a high mountain pass in the Rocky Mountains of central Colorado, US.  The pass is located on the Continental Divide of the western US at the southern end of the Sawatch Range along the border between Gunnison and Chaffee counties, approximately 25 miles (40 km) west of the town of Salida.  The pass carries US Highway 50 over the Sawatch Range providing a route between Tomichi Creek in the upper basin of the Gunnison River on the west and the South Arkansas River on the east.  The pass can be traversed by all vehicles under most conditions and is generally open year-round.  However, 7% grades exist and the area is prone to heavy winter snowfall which often results in temporary closures during severe winter storms.  The highway does have some three-lane sections and runaway truck ramps are located about halfway down both the eastern and western sides of the pass.  Ten curves have a 35 mph (56 kph) advisory speed and one 30 mph (48 kph).  The West Descent has a 6% grade for 9 miles.  The East Descent has a 6% grade for 10 miles.

The climb up Monarch Pass begins at 8,184 feet (2494.5 m) and climbs over 3000 feet (914 m) to the summit with a steady 5-8% grade.  We were lucky enough to be traversing the eastern descent, so we got that extra mile (1.6 km) of steep grade.  Monarch Pass is rated as the #19 most feared road to drive in the US, especially during the winter due to heavy snowfall, strong winds, and several known avalanche areas.  The steep grades and sharp curves combine with a lack of shoulder or guard rails to make this route particularly hazardous.  As we neared the summit, we saw signs for “active snow removal” ahead.  The summit was covered in snow (thankfully not on the road) and a dense fog set in.  I did not know if that might be better as I could not see the drive awaiting us.  The fog lifted as we descended and Melissa looked out the side window into the 300 foot (91 m) drop to the trees below.  She kept her eyes directly ahead for the rest of the descent.  We crept down the mountain, only periodically applying the brakes.  A harrowing 25 minutes later we were down.

THOUGHTS: After Monarch Pass Melissa told me we are never going to take US Highway 50 again.  The problem is, unless you avoid Colorado entirely you will need to take some risk to cross the Continental Divide.  I had taken all these passes without incident when driving a car.  It was vastly different in a motor home towing our Jeep.  When we tried to find the number of annual fatalities on the road the site said, “it varied”, but they did occur “periodically”.  Spending six weeks driving 5000 miles (2495 km) across much of the southern US (Arizona to Florida) gave me a new perspective on the drivers that supply the US with 72% of domestic tonnage (11 to 13 billion tons/10 to 12 m tonnes) annually, valued at more than US$13 trillion.  These trucks do not stop on a dime, so give them a break.  Act for all.  Change is coming and it starts with you.

Moab

March 25, 2026

I moved to Salt Lake City in 1979 to attend graduate school.  I grew up in Kansas (various), and was used to living in towns surrounded by agricultural fields or the remnants of the big bluestem (Andropogon gerardi) that dominated the tall grass prairie.  What I found in Salt Lake was the Uinta Mountains on one side and a salt desert on the other.  While I quickly adapted to the mountains (skiing) I did not like the desert, finding it hot, salty, and barren.  After a few years I was drawn to the archeological sites of the four corners region and southeastern Utah (Anasazi cliff dwellings).  I later worked for the Division of State History mapping and encoding sites and participated in several archeological surveys in the area.  The more I worked in the area the more I was drawn to it.  By the time I left for California I found it was the desert I missed the most.  The largest city in the area at that time was the declining town of Moab with 4000 people.   

When I went online, I found Moab is the largest city and county seat of Grand County and is known for its dramatic scenery.  The population has risen from 4800 in 2010 to 5400 at the 2020 census.  Moab attracts lover 3 million tourist annually, mostly visitors to the nearby Arches (4 miles/6.5 km) and Canyonlands (22 miles/35.5 km) National Parks.  The town is also a popular base for mountain bikers who ride the extensive network of trails, including the Slickrock Trail.  Off roaders also come to for guided Jeep tours and the annual Moab Jeep Safari.  Moab has experienced a surge of second-home owners as the mild winters, and enjoyable summers attract people to the area.  This mirrors other resort towns in the American West and controversy has risen over the new residents and their houses, many of which are unoccupied most of the year.  Moab citizens are concerned the town is changing like the towns of Vail and Aspen in Colorado.  This means skyrocketing property values, a rising cost of living, and corresponding effects on local low- and middle-income workers.

I was anxious to revisit the quaint town of Moab and enjoy the solitude of the surrounding desert.  Melissa had been talking about visiting the area I loved ever since she heard stories of the many weekend trips taken by me and my son Alex.  Often, we would not see another human from the time we left the main road until we returned.  The desolation and isolation that had initially turned me off became the basis for my attraction.  What we found now was dramatically different.  Construction started several miles outside of town, with light industrial sites, gas stores, and fast-food chains.  These were interspersed with motels, residences, and RV parks.  The street was lined with businesses offering scenic tours by jeep and mountain bike.  If you did not want a tour, you could rent either to go on your own.  There were offers for ziplines along the canyon rim and plane rides.  What struck me most was the change from quiet isolation to the hundreds of people walking or biking along the main throughfare.  While the residents may be only 1500 more than I remembered, tourists overwhelmed the city.  Moab embraced the niche market of adventure tourism. 

THOUGHTS: Melissa and I camped our RV about 15 miles (24 km) north of Moab in the new (2021) Utahraptor (yes, found there) State Park.  This was centrally located to spend time at two sites I fondly remember, Dead Horse Overlook and Arches National Park.  We found Arches often has long wait lines to enter (exceeding 60 minutes from spring through fall) and the park temporarily restricts access if parking lots fill up.  We opted to go straight to Dead Horse.  Here again we found 100’s of people.  Most were hiking or mountain biking the roads and trails that wind through the park.  My recollection was seeing one or two other cars at the overlook.  While you can go home again, it may not be recognizable.  Still, the trip was worth it and the scenery spectacular!  It was worth the crowds.  Act for all.  Change is coming and it starts with you.

Burros

March 19, 2026

Several days ago, we camped in the Homolovi State Park in Winslow, Arizona.  I was excited to camp in the park as it contains the remains of two pueblos along with a petroglyph panel.  Homolovi now serves as a center of research for the late migration period of the Hopi from the 1200’s to the late 1300’s.  The park is over 4000 acres (1618.74 ha) and includes a visitor center and museum, various trails and the campground where we spent the night.  We arrived early as I wanted to explore the ruins and walk the trails.  As we entered the gated park, we saw a sign indicating it was an open range (animals roam free inside the fenced area).  We explored the partially excavated Homolovi II site and then took the kids for a walk around the parking lot.  The docent at the museum had shown me where the petroglyph (pecked rather than drawn) panel was located and that became our second stop.  On the way to the ruin, we noticed several animals grazing off in the brush.  On our return the animals had moved closer to the road, and we saw they were wild burros. 

When I went online, I found Wild burros (Equus asinus) in Arizona are primarily found in the western desert mountains, most famously in the historic mining town of Oatman, where they roam freely and interact with visitors.  The burros are descendants of 19th-century mining pack animals.  The protected animals can also be found near Lake Pleasant, near Peoria, Arizona.  While the burros are a popular attraction, they are wild.  They can bite or kick and feeding them is discouraged to protect their health and safety. The burros are often found in various Bureau of Land Management (BLM) areas in western Arizona and are particularly active during early morning and late afternoon.  There are over 10,000 estimated wild burros in Arizona, which is far above the sustainable level for the environment (less than 1,500), leading to BLM efforts to manage the population and reduce their impact on the desert.  The burros are protected under the federal Wild and Free-Roaming Horses and Burros Act (Public Law 92-195) of 1971, which means it is illegal to harass or harm them.  BLM suggests the best way to see the animals is from a distance, without pulling off the road.

While the burros we saw at Homolovi were from a distance, we found them close when we arrived at our Lake Pleasant campground.  There was a group of three who were feeding among the campers across from where we were assigned.  I had been wary of camping at several of the “Horse Motel” campgrounds set up to accommodate equestrian travelers along our route as I was unsure how the kids would react to the large animals.  Now I had no choice as we were invading their protected land.  We kept the kids inside while we set up camp and placed the night shade over the front windshield of the RV.  I checked outside before taking the kids for a walk to burn off energy before feeding them.  We all settled in together inside the RV as it was too hot to be outside.  Later that evening I put on their lease to take them out for a final trip.  I always go out before them to make sure I have control of the lease.  When I opened the door, Zena nearly knocked me down as she tore through the opening with her VERY loud protective bark.  One of the burros was standing about 15 feet (3 m) from our front door.  I do not know who was more surprised, the burro, the dogs, or me.   

THOUGHTS: While wild burros are predated by mountain lions, this is not enough to keep their population in check.  The Wild and Free-Roaming Horse and Burro Act charged BLM with managing wild burros in a thriving natural ecological balance with other plants and animals to maintain healthy ecosystems.  Wild burros removed from management areas due to overpopulation, emergency situations, or through nuisance are available for adoption through the BLM’s Wild Horse and Burro Adoption Program.  Protecting an invasive species is always a fine line.  Act for all.  Change is coming and it starts with you.

Verde Valley

March 18, 2026

After battling the winds across the Panhandle region, we were home free as we climbed into the Ponderosa pine (Pinus ponderosa) forest that surrounds Flagstaff, Arizona.   The Coconino National Forest is located within the world’s largest contiguous Ponderosa pine forest (yes, where the name Ponderosa Ranch comes from on the long-running TV series Bonanza).  These dominant, tall trees are famous for their orange-brown, puzzle-like bark that smells like butterscotch or vanilla.  We also passed three National Monuments along the route that were extant cliff dwellings of the prehistoric Ancestral Puebloans (Anasazi).  Like so many other first-time travelers to Arizona, we were surprised to find the dense forest of the Kaibab Plateau rather than the stark desert we associated with the state.  As we traveled south out of Flagstaff the forests diminished and the saguaro cactus (Carnegiea gigantea) took over as we began to drop in elevation.  The saguaro is the largest cactus in the US and acts as a vital, long-lived (up to 200 years) keystone species in the Sonoran Desert.  While I had anticipated the saguaro, I was not prepared for the Verde Valley descent.    

When I went online, I found the steep grade on Interstate 17 descending from Flagstaff toward Phoenix is often referred to as the Verde Valley grade or simply the I-17 mountain corridor.  This stretch includes a sustained 6% grade for roughly 13 miles (21 km) between Flagstaff and Camp Verde, Arizona that requires runaway truck ramps.  The stretch also includes another steep section for southbound traffic near Black Canyon City.  The route is known for high speeds, steep inclines, and sharp curves and is often cited as one of the most treacherous connections in Arizona.  While Flagstaff sits at 7000 feet (2133 m), Phoenix rests in the Verde Valley at an elevation of 1,086 feet (2133,6 m).  Although only 145 miles (233 km) apart, the great difference in elevation result in drastic climate changes.  Flagstaff is typically 20F to 25F degrees (36 C to 45C) cooler than Phoenix on any given day all year round.  This was a descent we were unprepared for.

Our first indication of the Verde Valley downgrade was a sign saying, “6% grade ahead.  Trucks and vehicles towing trailers use lower gears.”  We were driving the RV and pulling our Jeep behind.  We qualified for the warning.  My first thought was I was glad I was not driving.  Then, I wondered if I should offer to drive.  Neither of us had driven anything close to these conditions, so I was not sure I could do anything better than Melissa.  Instead of pulling over, Melissa asked for suggestions on how to drive.  She slowed down and I clicked on the emergency flashers as we began our descent.  The first thing we tried was shifting into 2nd gear.  That did not last long as the engine RPM climbed close to the red line.  I had just read an article online about the best way to slow your RV when on a steep grade and it suggested to make hard brakes followed by taking your foot off the brake.  Melissa shifted into Drive and periodically punched the brake to slow down.  There were also reprieves on the descent where it would level off or even ascend for short distances.  Melissa did a great job, and we got down without incident.

THOUGHTS: Toward the end of the Verde Valley descent, we passed a truck parked along the side of the road with its brakes smoking.  I was glad the driver was able to stop (and that we had avoided a similar situation).  I was also proud of the way Melissa had handled driving.  It was tense for me, and no doubt more so for Melissa.  I knew we had to retrace this route on our way to Utah, but this time we will be going up, a whole new set of problems.  This last month has been an amazing immersion into the diversity of the US.  We traveled from the Ozarks to the Florida Atlantic coast, then to the high plateau and desert of Arizona.  The people have been just as diverse.  Rather than a detriment, diversity is what defines our nation.  Act for all.  Change is coming and it starts with you.

Trails

October 10, 2025

We had decided to take our second trip out in our newly acquired RV just as the US government decided it was not in their (our?) best interest in keeping the government operational.  While many of the National Parks are at least partially open, we learned the Corp of Engineers location we planned to visit was shut down.  We have some neighbors who were also planning on the same trip and learned they had booked a private location about an hour away.  We already had two events scheduled for the week and thankfully these were both centrally located to the RV Park.  Melissa made reservations and we took off Tuesday morning.  The park described itself as “rustic”, and when our neighbors arrived, they called to make sure we were comfortable with what that meant.  Melissa and I both thought the unpaved location along the Mulberry River was going to be perfect.  There was even a trail/road that led back along the river that was perfect (and away from other campers) for walking the kids.  The trail provided a moderate walk that wound through the trees and wildflowers.

When I went online, I found a trail, also known as a path or track, is an unpaved lane or small paved road generally not intended for usage by motorized vehicles, and usually passing through a natural area.  However, it is sometimes applied to highways in North America.  In the UK and Ireland, a path or footpath is the preferred term for a pedestrian lane or hiking trail.  In the US historically, the term was used for a route into or through wild territory used by explorers and migrants (i.e., the Oregon Trail).  A “trace” is sometimes used as a synonym for trail (i.e., the Natchez Trace).  Some trails are restricted to only walkers, or cyclists, or horses (equestrians).  During the winter these same trails can be used for snowshoeing or cross-country skiing.  Others, like the bridleways in the UK, are shared and are jointly used by walkers, cyclists, and equestrians.  Although most trails ban motorized use, there are unpaved trails used by dirt bikes, quad bikes, and other off-road ehicles.  This is especially true for extreme sports and rally races.  In places like the mountainous Europe (Alps), trails are also used by alpine agrarian communities for moving cattle and other livestock.

Over the last several days I have been walking the trail along the river marveling at the amazing views.  The track passes above the river and in places rises on the bluffs that overlook the water.  Being an avid fisherperson, this has given me pause to dream of climbing down the slope and fishing the fast water and pools that dot the river’s course.  Several days I did exactly that, although I did so by following the rocks at th e water’s edge.  My other pleasure has been seeing the patches of Tatarian Aster (Aster tararicus) and goldenrod (genus, Solidago) that line the trail.  This is the freedom and escape we had hoped to find when we decided to start RVing.

THOUGHTS: Following most modern-day trails is a far cry from the trails that cut through the thick forests and lush grassland that filled North America when the European explorers and settlers first arrived.  These trails possessed unseen dangers (animals and nature) along with the impressive beauty.  Still, I can get a glimpse of the wonder of days gone by.  We need to work hard, an together, to preserve those areas that still exist for future generations to enjoy.  Act for all.  Change is coming and it starts with you.

Catchments

June 09, 2025

I found it fitting after blogging last month about the wildlife structures in Southern Colorado that allow animals to safely cross highways to come across an article in Sunday’s paper addressing the drought wildlife faces in the Arizona desert.  The article began with the parade of animals coming to the human-made watering hole on a night in May.  First a coyote (Canis latrans), then a gray fox (Urocyon cinereoargenteus), followed by a great horned owl (Bubo virginianus), and finally a herd of mule deer (Odocoileus hemionus).  As dawn broke the watering hole began to serve its daytime visitors.  These were the scaled quail (Callipepla squamata), ravens (Corvus corax principalis), vultures (Cathartes aura), doves (genus Streptopelia), and the occasional lizard (genus Tupinambis).  This activity was recorded at the “Teddy Bear” water catchment, nicknamed for the teddy bear cholla (Cylindropuntia bigelovii) that grows around it.  This is one of the thousands of catchments managed by Arizona Game and Fish (AGF) built to boost game numbers for hunting and compensate for habitat fragmentation.  The catchments have satisfied thirsty animals since the 1940’s.

When I went online, I found Teddy Bear (catchment No. 436) was built to draw deer away from the Central Arizona Project (CAP) Canal.  The site has a large sheet of metal that directs rainwater into a gutter and feeds it into an underground tank.  The water resurfaces a few yards away as a square of slick green in the arid desert.  A fence surrounds the catchment to keep livestock out yet allows wild animals in.  Joe Currie, AGF habitat planning program manager, said the catchments are a great support for creatures who live in Arizona’s unforgiving deserts.  Many animals can only live a few days without water or the water-rich food the catchments provide.  When they were built, many of these watering holes thrived on the more consistent rain.  Now, state officials say the drought has forced them to use trucks, and even helicopters, to keep the catchments full.  Each year AGF hauls more than 1 million gallons of water to nearly 3,000 catchments.  As severe drought deepened in Arizona in 2024, hauling has picked up.

After decades of long-term drought throughout the Southwest, Arizona suffered its hottest summer on record in 2024 and a near-record dry spell back-to-back.  These short-term drought conditions persisted through the first half of 2025.  Every region of Arizona has been under an official drought designation since January.  The Forest Service and Bureau of Land Management own two-thirds of the catchments.  Those departments used to have robust wildlife management programs but now have no budget to maintain the sites.  Arizona has taken responsibility for the entire network, spending roughly US$1 million each year maintaining the catchments.  Helicopter deliveries, with the same equipment used to dump water on wildfires, cost more than US$10,000 each.  The AGF maintains a donation program where donors have contributed US$1.3 million since 2018.

THOUGHTS: Along with the catchments, Arizona has invested in wildlife structures for animals crossing highways and neighborhoods.  Both allow animals to reach the water and food they need in dry times.  The CAP also has 30 crossings dispersed along the canal system.  These linkages also support genetic diversity in animal populations and allow wildlife to adjust to the effects of climate change.  Deer are ruminants (like cows) and cud-chewing animals in dry areas struggle to digest the vegetation.  Deer stuck in dry areas might also give birth to fewer fawns.  The same goes for a range of other species.  While hunting may provide emphasis (and funding) for the structures and the catchments, like most conservation projects they serve the entire ecosystem.  If showing how such projects provide for human interests works, I say, “make it so #1!”  Act for all.  Change is coming and it starts with you.

Traction

January 14, 2025

Yesterday I decided it was time to get out into the weather and take the kids for a walk.  I decided to go to the lake as it was more open and had a better probability for the parking lot to be cleared by road crews.  The temperatures in the morning were below freezing (-0C) but were set to warm up to 40F (4.5C) by the afternoon.  I did have two concerns.  The first was the possibility for windchill which would negate any increase in temperature.  I decided to dress for the cold.  That meant a pair of long johns under my sweatpants.  Then a tee shirt, a long sleeve undershirt, and a long-sleeved thermal undershirt.  I topped this off with a light ski jacket.  The first concern was covered.  The second concern was the potential for ice and snow on the spits we walk at the lake.  The kids have been romping in the snow in the side yard, and I knew this would not be their concern.  That is different for me and was my reason to shovel over the weekend.  Melissa was a runner when we met and one of her first Christmas presents was cold weather gear for running in Kansas.  That meant running gloves, hand and foot warmers, and a set of spikes in a rubber harness.  The spikes were billed as “everyday traction aids”.  The spikes should provide the traction I needed to walk the kids.   

When I looked online, I found Merriam-Webster defines traction in several ways.  The first definition (and applicable for me) is “the adhesive friction of a body on a surface on which it moves”.  A variation of this meaning says traction can refer to “a pulling force exerted on a skeletal structure (as in a fracture) by means of a special device” (splint).  A second definition is “the force exerted in the act of drawing or being drawn”.  The third meaning took a different approach with “the support or interest that is needed for something to make progress or succeed”.  This indicates something “gains traction” as people begin to accept and/or adopt an idea or methodology.  Finally, traction refers to “the drawing of a vehicle by motive power”.  Here a tractor is something that pulls something else.  This is often a piece of farm machinery or the part of a big truck that includes the engine and the cab.  The word tractor comes from the Medieval Latin “traction”, or from the Latin “trahere”.  The first known use of traction in English occurred in 1608, in the meaning defined by the second sense.

I was intrigued by the spikes guarantee to provide traction as I walked the kids.  After I bought them, Melissa had never had an occasion to use them.  They sat (in the original package) in my closet along with our shoes for 15 years.  When we pulled into the lake for our walk, I found the parking lot was generally clear of ice and snow.  Even the roads leading out to the end of the spits were clear, even though the grass on either side was snow covered.  I left the traction spikes (still in their packaging) in the car and started on our hike.  The temperature was higher than forecast at 45F (7C) and my decision to bundle against the cold seemed unnecessary.  Neither of my concerns were warranted.  I was toasty in my layers and the snow and ice were gone.  However, I was not anticipating the mud.  The ground was mostly frozen, but my four-wheeler buddies had been taking laps in the snow and over the roads.  As we walked the spits, Loki’s legs and underbelly quickly became covered in mud.  We took most of our laps circling the parking lot.  Luckily there was enough snow on the grass to wash Loki off before I let him back into the car.

Thoughts: This was one of the (rare) occasions where I over planned for the cold and loss of traction.  Even though I did not need all the extra layers, it was nice to be warm and snug while we walked.  The traction aid I bought for Melissa went back into the closet next to my shoes to wait for another day.  I do not know if my over planning can be accredited to experience or unwarranted caution as I age.  As a Boy Scout our motto was “Be Prepared”.  That is still a good motto for hiking, camping, and even for life in general.  Act for all.  Change is coming and it starts with you.

Mud Tracks

November 06, 2024

We have received heavy rain over the last two days, and I tried to keep the kids out of the side yard. I monitor them when I do let them out to make sure they are not mischievous (Loki is a digger and Zena is a roller) and end up covered in mud. Today the rain stopped, and I decided to brave our walk site at the lake. A portion of the walk is on a paved parking lot, but the majority covers packed dirt tracks that lead out to the end of two spits. We were the only ones there when we arrived to begin our walk. We walked to the end of the first spit and while it was wet, we were able to pick our way through the puddles without getting our paws muddy. As we were coming off the spit two 4-wheel drive pickups pulled out onto the other spit and began to cut mud tracks through the vegetation. As we walked around the paved lot on the trail the trucks moved to the area we had just left. This had a wider area that had been torn up by previous off-road activity. It did not take long for one of the trucks to get stuck axel deep in the mud. This was obviously why they had come in the first place. After extricating the truck, they drove to the boat ramp and took selfies of the mud covered truck to share with their friends. Teenagers in pickups are not the only ones that leave mud tracks.

When I looked online, I found one of the more famous mud tracks is located at Racetrack Playa in Death Valley. Racetrack playa is approximately 3 miles (4.8 km) long and 1.2 miles (1.9 km) wide and is located at a height of 3708 feet in a north-south valley east of the Panamint Range within Death Valley National Park. The playa receives only 3 inches of annual precipitation and is bounded on all sides by north-south ranges rising 1500 to 2000 feet (457 to 610 m). The surface of the playa is mainly dried clay and provides a hard, smooth, and level pavement. The sailing stones, also called sliding or walking rocks, move and inscribe long tracks along a smooth valley floor without animal intervention. The movement of the rocks occurs when large, thin sheets of ice floating on a brief winter pond break up in the sun. Rocks weighing up to 705.5 pounds (320 kg) travel across the playa and leave mud tracks. Stones with rough bottoms leave straight striated tracks, while those with smooth bottoms tend to wander. The mud trails differ in both direction and length. Rocks that start next to each other may travel parallel for a time and then one abruptly changes direction to the left, right, or even back to the direction from which it came. This phenomenon has been documented since 1948 and is not unique to Racetrack Playa. Tracks in the mud have been observed around the world.

Traditionally, these rocks were considered to be pushed by wind over a wet and slippery playa surface but observations from 2014 called this assumption into question and several aspects of the mud tracks remain a mystery. A thorough system was put up to investigate the rock movement that included a weather station near the playa, time-lapse cameras centered on the southeast corner, and 15 GPS-equipped boulders on the surface. The researchers went to the location for maintenance and data retrieval 5-8 times per year and from November to March of each year the time-lapse camera recorded hourly conditions. Interwoof GPS loggers were also installed in limestone blocks northeast of natural stones and captured GPS and temperature data every 60 minutes. The GPS trackers began recording constantly at one-second intervals after being triggered. The shape of the shallow lake named Ontario Lacus on Saturn’s moon Titan has been compared to that of Racetrack Playa.

THOUGHTS: Despite the signs and barriers forbidding driving on the surface and making mud tracks posted along parts of the playa, park rangers still find new tire tracks on it every couple of years. The walking rocks will not slide if the surface is defaced. Destruction of such natural wonders takes decades to repair. Act for all. Change is coming and it starts with you.
