0 - 0.0117 Ma

ID: 3371283
Modern flood-plain deposits

Age: Anthropocene (0 - 0.0117 Ma)

Description: Gray-brown to light-red clay, silt, and fine-grained sand; weakly consolidated by clay and calcite cement. Deposits include some lenticular gravel, subangular to rounded pebbles, and cobbles; intertongue with or are overlapped by adjacent fluvial or eolian surficial deposits (Qs, Qv, Qa1, Qps, Qd, Qes). Forms shallow flats 0.5 to 1 m (2 to 3 ft) above stream-channel deposits (Qs). Subject to overbank flooding in lateral and vertical sense along Little Colorado River and larger tributary valleys. Supports sparse to light growths of sagebrush, grass, tumble weed, and thick growths of salt cedar (tamarisk) trees and other high-desert shrubs that trap and accumulate more recent eolian-sand deposits. Thickness, 0.05 to 2 m (2 to 6 ft)

Glen Canyon Group

Age: Mesozoic (174.1 - 227 Ma)

Stratigraphic Name: Navajo Sandstone; Kayenta Formation; Moenave Formation

Description: Conspicuous red, cross-bedded Wingate Sandstone and the conspicuously cross-bedded, eolian, red to buff Navajo Sandstone form prominent cliffs in northern Arizona. These two sandstone units are separated by variably colored siltstone, silty sandstone, and sandstone of the Kayenta and Moenave Formations. (180-210 Ma)
