Nankoweap Mesa — The big sky-island that forms the east wall of Nankoweap Basin which is the upper zone of Nankoweap Canyon. Nankoweap Butte looks big from below but just a minor bump in a vast landscape from the top.

Routes — Non-technical but difficult off-trail route to the summit (see Nankoweap Mesa Route).
