Big Bend also offered excellent views of numerous rock climbers going straight up the essentially vertical canyon walls. It is again difficult to convey the right perspective here. A shot taken to show the sheer height of the canyon wall would make the climbers into dots too tiny to see on an image of this size. Hopefully this picture will give some idea of what we saw. Canon 100-400L at 400 mm, ISO 200, f/5.6, 1/200 second on a tripod.
