Geology

Grand Canyon Dutton Pt, Masonic Temple
Huxley Terrace (elevation highpoint-5630 ft) and the remnant, small, massif of Wallace Butte (5209 ft)

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.
