Ochoa Point is a 4,761-foot-elevation cliff-summit located in the easternGrand Canyon, inCoconino County of northernArizona,US. The landform is on a southeast ridgeline fromApollo Temple, with the Ochoa Point prominence on its southeast terminus. Ochoa Point is 1.0 mi from Apollo Temple, 1.5 mi northwest from the southeast-flowingColorado River, and 3.5 miles due-west from the south terminus of the East Rim, Grand Canyon (Palisades of the Desert).

Ochoa Point’s southwest cliff-flank, and Apollo Temple’s southwest arm (southeast flank), contain the dp-black Basalt Cliffs (composed ofCardenas Basalt); the Cardenas Basalt lies upon brilliantly colored reddishDox Formation low-angle, erosion-slopes (units 5 and 4) of fiveUnkar Group members. What makes Ochoa Point distinctive, the next rock unit above is the colorful, layered (banded),Nankoweap Formation. These rock layers all slope at approximately 15 degrees, and are topped by the short-cliff, horizontalTapeats Sandstone (the Tonto Platform, and called theGreat Unconformity).
