"Cliff" was too simple a word to denote the geological phenomenon rising above him. It was not a sudden vertical wall so much as a rapid increase in the slope of the ground that became fully vertical, and even developed into a bit of an overhang, twelve or fifteen feet above. And it was not a simple monolith, but a junk pile of boulders, tenacious vegetation, and packed soil that just happened to be really steep. Its top was out of view, but he knew it to be about fifty feet above. Anyway, it was now sheltered enough that he felt he could take a decent crap and so he hopped up and down several times, reversing his direction by degrees, and began to fumble with his belt.
