Geology


The large Huxley Terrace (photo), is composed of the Supai Group – 4 units. Notably, rock units 4 and 2 are cliff-formers, and the entire Supai Group sits on the cliff-former (and platform-former) of the Redwall Limestone.

For Wallace Butte, geologically it is a cliff and slope-former remainder – of Supai Group units 2 and 1 (Manakacha Formation, Watahomigi Formation). The cliffs of the Manakacha protect the slope-former below; (with the height of 349 ft, the landform is triangular, thin, and ~350 ft long, by ~150 ft wide); (See here: ) both units are on the top platform of the Redwall, the Redwall Limestone upper platform being a common rock unit throughout the Grand Canyon as landform points, (surrounding prominences), or as platforms supporting numerous rock units above, nearby examples being Geikie Peak and Whites Butte.
