As I approach my destination down here in the canyon, Arnold Horse Camp, I pass by a small area where the Creek has not completely dried up yet. There's not much water left, but I take a note of it in case I have a problem with the water at Arnold Horse Camp and have to backtrack to this location to purify some water. It looks bad, but at the same time last year I drank from similar residual pools of water along here (filtered of course) and the water tasted quite good (to my surprise)!
