Cosmic Ashtray and Neon Canyon/Escalante River Petroglyphs

9/13/2023

4 Comments

 
A four-mile journey across pristine slickrock brings you to this wondrous geologic feature in remote Grand Staircase-Escalante National Monument.  Nearby, a huge petroglyph panel representing various cultures looks over the Escalante River near Neon Canyon.

For the Geo-curious
Netoff, D., et al. 2009. Aeolian activity at a giant sandstone weathering pit in arid south-central Utah. 
Considerations:  There's no guarantee that cairns or rock ducks will be marking the route across the large slick rock expanse on the approach.  Experience with navigating using apps, topo map and compass is highly recommended.  Watch the weather, don't enter canyons or rivers when there is thunderstorm/flash flood forecast, watches or warnings in the area.  These hikes are on slick rock in open country.

Miss you Jimmy
Jimmy Buffett, singer/songwriter who cheered up millions of us with his concerts and fun, uplifting lyrics passed away September 1, 2023.  "Come Monday" plays over and over in my head.  Thanks for the music for us "boomers" and other generations, your fun concerts and for your love of the sea.

 Cosmic Ashtray
The Cosmic Ashtray, AKA "Cosmic Navel" is an astonishing sight to behold after a suspenseful four-mile hike across a sea of slick rock, when it suddenly appears as a huge white sandstone pothole filled with deep orange sand, a large rock stashed inside it.  This "weathering pit", also called "Inselberg (island mountain) Pit" because of its 10-meter high rock pedestal is the largest on Earth.  It has erosional features that resemble similar discoveries on Mars.  Wind continually changes the pit dune's orange sand shape and depth.  Based on Colorado River erosion rates, a study estimates this pit is 216,000 years old.

We talked to a bartender, a life-long Escalante rancher who had hiked Cosmic a few times.  He has climbed into the pit sand by tying a rope to a shrub!  We didn't find a hook in the pit wall.  We got to talking about Hole-In-the-Rock Road, one of the few that gives access to Grand Staircase-Escalante and the Egypt trailhead we used for Golden Cathedral.  After we complained that the road was very wash-boardy and rough, he said the county (Garfield) used to keep it in better condition before it became a National Monument.   We've been down this road several times and this time it appeared to be in the worst condition.

If you look at an aerial photo of the Cosmic Ashtray (check out the Netoff study), an open tunnel into the pit indicates wind has carved this channel smooth, creating wind-abraded flutes on its sandstone walls.   Cosmic Ashtray is situated on a topographical high, between bedrock knobs.  Wind funnels through these sandstone knobs enhancing wind speed (the Venturi effect).  The orange dune sand comes from distant areas; it's larger-grained and therefore heavier than the sand of the eroded pit walls, so it accumulates in the pit.  

Fred hadn't seen photos of the Cosmic Ashtray weathering pit so he was amazed when we came upon it.  The beautiful journey across miles of undulating bare Navajo sandstone makes you feel small and remote in the middle of the Jurassic-age buttes, knobs, and deep, narrow canyons.  Moqui marbles, black embedded half-shells of iron concretions, and weird stained patterns pop up in the bleached and orange slick rock.  Polygonal fractures that resemble honeycombs decorate the white sandstone all the way to the top.  It will be fun to take friends next time without showing them a "preview" of Cosmic Ashtray just to see their astonishment at the sight of it.

A sequence of ducks (small rock pile trail markers) led us up a steep pitch where Cosmic slowly came into view as we climbed to a lookout (Point 5847).  At first, the northern-facing pit wall appears, followed by the tip of the pedestal rock in its center, and then finally its orange sand pit.  Great vantage point for photos.  Then you can climb back down and access the pit from its north entrance.
Petroglyph panel near Neon Canyon and Escalante River confluence
The day before the Cosmic hike, we had planned to hike to Golden Cathedral, a beautiful alcove with two large skylights in Neon Canyon, but as we neared Neon's opening, we heard thunder and saw clouds accumulating as we stood in the  Escalante River.  Knowing we had to hike up Neon, we took the conservative approach and turned around, hiking the Beeline trail back to the trailhead.  
​
Thunderstorms didn't occur until later that day.  We are planning on returning in a few weeks, so stay tuned!

We found the impressive panel of "older" and "newer" petroglyphs near Neon's opening, probably spanning 5,000 years.  This huge continuous smooth slab of desert-varnished sandstone along the Escalante River is a perfect place for various cultures to carve rock art.  
Picture
Egypt Trailhead sign for Golden Cathedral hike
Deeply pecked abstract geometric petroglyphs from the Archaic culture (3,000 BCE) have been on this wall for so long that they are "re-patinated," or covered with dark desert varnish.  Glen Canyon linear style anthropomorphs (resembling humans), and animals make up most of the glyphs.  Bear paws and human feet march to the top of the slab.  Ancestral Puebloans pecked bighorn sheep and broad-shouldered anthropomorphs during 1,000 BCE - 550 CE.  

We approached Neon Canyon from the Egypt trailhead along the "standard" trail which entailed three or four Escalante River crossings.  BEWARE OF QUICKSAND when walking in low water levels.  Our plan next time is to hike the Beeline route from Egypt trailhead to Golden Cathedral - this means only one river crossing near Neon Canyon entrance.  

With each Grand Staircase/Escalante visit, our list of places to explore expands as this spectacular ever-changing land seems to do.  As I write this, I'm sitting in Las Vegas airport waiting for a Chicago flight.  I keep thinking of the magnificent land of Grand Staircase-Escalante, feel a yearning to return to it.  As its silty yellow and orange rivers flow, the scent of pine and juniper fill its air, and its landscape turns bright orange and vermillion with sunrises and sunsets, I wish I was there to see it.  As always, so much to see and do, so little time....

The "Cosmic Ashtray" is an inselberg pit (insel = island, berg = mountain in German).  The orange sand blows in from remote places.  The center pedestal is ~ 10 meters high.  Climb knob 5847 to the north for a good view of its sand dune.

Neon Canyon/Escalante River Petroglyphs
Picture
Looking down at "Egypt" from the trailhead.  The route goes through alternating sand and slickrock.  Aim toward the dark round dome upper left in photo - along the Escalante River.  Neon Canyon's opening is at the base of this dome.  I couldn't find the origin of the name "Egypt".  This is an old stock route, so possibly an original rancher, upon seeing this wide, sandy bench said, "Sure the heck looks like Egypt!"

Picture
These abstract petroglyphs are more deeply incised and re-patinated (covered with desert varnish); they probably older than the anthropomorphic (representing humans) petroglyphs seen on left side of panel.
Picture
Lots of petroglyphs superimposed over older ones.  Some of the more recent are from cowboy Charles Hall in 1881, who made his cursive signature under the undulating snake petroglyph.
Picture
These petroglyphs are located toward the left part of the panel and are lighter (desert varnish has not fully re-covered them), so they are probably made more recently than the abstract, re-patinated images.

    Exploration documentaries          –  "explorumentaries"  list trip stats and highlights of each hike or bike ride, often with some interesting history or geology.  Years ago, I wrote these for friends and family to let them know what my husband, Fred and I were up to on weekends, and also to showcase the incredible land of the west.

    About the Author
    Sue Birnbaum

    A  trip to Jumbo Rocks Campground in Joshua Tree National Monument 40 years ago sparked my passion for hiking, exploring, and learning about desert ecosystems.  I met my husband Fred on Mt. San Jacinto.  We've explored the American West together; we love this land and I hope to inspire you to get out and explore through my photographs and trip descriptions.
    In 1992, Ray Wilson and I conceived the first Cactus to Clouds hike which climbs over 10,000 feet in one day to the summit of Mt. San Jacinto near Palm Springs, California.
