The Supai Group sits on the resistant cliff-forming, typically massive Redwall Limestone, (as in the connected Tower of Set southwards). The base of the Redwall has a short, but resistant cliff of (3rd-unit) Muav Limestone. Below the Muav are units 2 and 1 of the 3-unit Tonto Group, the colorful dull-greenish Bright Angel Shale, and dp-brown Tapeats Sandstone.
