In April of 1977, I spent several days on the Lake Pyramid Indian Reservation. Pyramid Lake is a terminal dessert lake, thirty-five miles northeast of Reno, Nevada. I camped at the southwestern corner of the lake at the base of some massive Tufa spheroids. I was attracted to this particular campsite because of the presence of a large rock that had separated from the towering rock wall and rested four feet out from it in the dessert. The impression of where this rock had been attached was clearly visible on the wall. Before establishing my campsite I built a wall of rocks connecting this isolated rock to the rock wall from which it had broken loose.
