Evidence of blocks of rock sloughing off the walls of Phoenix Canyon. The large X , the snake-like pattern below it, and the + pattern to its left, almost look like hieroglyphics although formed by natural processes. Curiously, thesloughed off area does not have the ubiquitous hole pattern of the rock below. (Image credit: NOAA OKEANOS EXPLORER Program; Our Deepwater Backyard)
