I'll share three incidents - one was non-photographic.
First was in a Laguna Canyon, southern California. It has a large (20-ft? diameter) sandstone boulder half sticking out the side of the 45-degree cliff. I crept out on it a ways and sat down with my feet flat in front of me. At some point I felt a little slip-and-stop - it might have been as short as 1/4 inch. But it made me realize sitting on slanted friable sandstone was not a good idea - it would be about a 50 ft drop over the edge.
Second was hiking up the mountain trail at Castle Crags (I think) in northern California. Lightweight clothing, maybe some water, loaded camera bag. After eventually zigzagging up the trail, the trail started to level off into to an area with no plants - a bald head. The sun was getting lower and I knew I was not going to get to the "end", so I decided, prudently, to call it a day and go down. However, I could not find the trail and spent a fair amount of time poking around dead ends before I finally found it.
Third was at Amboy crater near Amboy CA.
Very hot Sunday mid-morning. Drank some water and started the mostly-flat mile hike toward the crater. Hot sun-baked black lava. Out a ways was a bench and cover - made out of aluminum :-( I did not stay there long. Onward, to and up the lip of the crater.
Now I'm really hot and tired with nothing but dark lava to rest on. I did not even cross the crater bottom trail (above), but just returned to my car.
This is the view "down".
For about 15 minutes, I felt woozy and just sat in the air-conditioning until I felt I could drive. I could easily have passed out somewhere and not be found for days.
