Abandoned Hiking Climbing Gear - Common?

Abandoned Gear Mystery Solved

I connected online with friendly ex US Marine who hiked out to Trellis Canyon twice, first in 2015 and then again March 2017. The second time was with a buddy. Their goal was to explore a supposed tunnel from the mouth of Trellis Canyon that went under the Panamint Mountains and out somewhere. I ignored all that woo woo lost city stuff but focussed on his hiking report. His buddy got sick as they entered the mouth of Trellis Canyon so they headed back to their car park off Highway 190 somewhere. Along the way they abandoned their canyoneering gear to save weight. This is what I stumbled across December 2021 that had been exposed to the harsh desert weather since March 2017. He shared this image.
