Even though we were in a desert, there was plenty to see. We stopped at a group of irregularly shaped, volcanic rocks, and in the distance could admire their creator: the semi-active, still-smoking Ollague Volcano. The most famous rock formation is the Arbol de Piedra, a 26-foot stone in the (very approximate) shape of a tree. Its trunk is long and narrow, and the day the entire thing topples over surely can not be long off.
