Think TINY. There were over a dozen climbers on El Capitan the day this picture was taken. Almost in the center of the rockface you should be able to see a tiny speck in a long, slightly diagonal crease; the rock is a tannish color. That's one of the climbers. Below him, lower center of the rockface - the rock is more grayish - you can see a small diagonal gash with a speck on either side of it. Those are two more climbers. It takes several days to climb the rockface and we were told that the climbers, of course, sleep on the mountain either hanging, or resting on a ledge.
