This is way up canyon, on the left. Probably across from the Pyramid; maybe even beyond.
Hike up Rattlesnake Canyon until the canyon is choked by big boulders; keep on hiking, past the turn off gully for Valley of the Kings. Soon you will see the Udi Buttress on the right; it has a reddish hue to it, with a suicide-like grey slab just beyond it (The Udi Slabs).
