Historic safety hazards

A lot of my work takes me to the most remote places of Joshua Tree NP, only accessible with a high-clearance 4WD vehicle, and then by hiking miles out. At these seldom visited places, I'll often come across abandoned mine shafts. This one drops about 100 ft. below. There are about 120 open mine shafts in the park, often accompanied by historic trash, structures, and old vehicles.
