Finally back in Death Valley! My DV trip will be a little different this year. I'm traveling with a friend from Europe for a few months. We spent a few weeks in DV circa 2017, so this year's DV trip is a mix of re-tread, nostalgia, and new adventures. I'll avoid posting much in the way of re-treads of hikes that I've already posted or well visited popular areas.
Anyway, let's get started!
This is actually a hike that I've been looking forward to for almost a year now, since I was out here in March 2024. "SEE HERE" or SEE HERE. This officially unnamed feature is visible from virtually any point on Badwater Rd and has always intrigued me. Last year I set out to visit this geologic anomaly for the first time and to uncover a few of it's secrets. What I found on those trips of course only whetted my appetite and left more questions than answers as always. In the interim I was contacted by a professor of geology and we talked at length about the make-up of this feature. It is down in the textbooks as “volcanic tuff”, as so determined by the great DV geologist Charlie Hunt (who's wife Alice also studied the area's indigenous history). Much of this outcrop more resembles sandstone than volcanic tuff and there are strata within it that contain sedimentary layers from an ancient lakebed. Perhaps the whole thing is somewhere in the middle, a tuffaceous sandstone with some lithic elements. Interestingly there is also a much whiter layer of ash/tuff below all of this that makes up White Tanks Wash at the base of this geologic feature. Someone with better geological credentials than me will have to break it all down for me someday.
This year I wanted to dig a bit deeper on both the geological and archeological make up of what I am calling the Tephora Sphinx, due to it looking like a lounging cat from the south. (Someday I will get a better photo with my telephoto...)
One of the first things I wanted to accomplish was to attempt to navigate the main canyon that splits the tuff essentially in two, if I could gain access. Last year I had only navigated most of the way around the perimeter of the landform and not inside of it.
Looking at the Tephora Sphinx from one of the many benches you have to scale on the hike in.
A closer look at the canyon that I am calling Ash Crack Canyon.
The first obstacle is getting into the enclosed bowl at the base of the canyon. There was a bit of a tricky section to this climb on the most obvious way in, but there was also a very easy bypass on the left side.
Looking in from the top of the bypass. Oof… looks like a long rock scramble.
Getting started.
Here is an exposed piece of the sedimentary layer poking through.
It was quite a rubble pile in places.
Looking back down canyon.
A very lovely section of narrows.
I was immensely surprised to see this arch poking out of the cliff. I generally wouldn't have thought that crumbly volcanic tuff would support an arch.
Eventually we were turned back by this ~20ft dryfall.
Looking back down canyon. I think there was a viable route (albeit in garbage crumbly rock) on the right here that would have gotten you around the fall. But with daylight fading, we wanted to try to navigate around the whole canyon from the above.
Looking back one last time.
We headed up the very steep sides of the rounded tuff. Which was quite grippy right up until it wasn't at all. The nature of the surface goes from 80 grit sandpaper to ball bearings on plywood as soon as you get caught sight-seeing.
It was quite a maze-in-the-sky to navigate between the eroded canyons.
Looking South towards our trucks and on to Shoreline Butte and eventually the Confidence Hills.
Looking towards DV proper.
Looking West into the Panamints.
Looking South from the summit of Tephora Sphinx.
Looking North towards Starvation Canyon.
At the head of the canyon. We had wanted to try from this end and meet our track in the middle of the Ash Crack, but daylight was getting away from us.
More of that lake bottom layer.
Odd human-looking “print” in one of the sedimentary layer. Suspiciously about 8-9” long as well. Haha.
Pushing our luck past sunset due to the fullness of the moon, the colors over the valley were phenomenal.
Just as our moon-shadows started to become visible we received quite a fright as we entered the final wash of the hike back: an angry burro huffing loudly at us from 25yrds away. I could only see the white diamond on his face in the moonlight because the coward was hiding behind a huge boulder to yell at us. After yelling back at him had no effect (but was a very cathartic way to bleed off the adrenaline), I also tried telling him that I had no interest in his burro harem, which also had absolutely no effect. So we just yelled at each other for a while until I was far enough across the wash that he finally shut up.
Anyway, let's get started!
