0 - 0.0117 Ma

ID: 3372386
Young alluvial fan deposits

Age: Anthropocene (0 - 0.0117 Ma)

Description: Southwest of Little Colorado River Valley (sheet 1): Gray-brown silt, sand, gravel, pebbles, cobbles, and boulders; weakly consolidated by calcite, gypsum, and minor amounts of salt cement. Silt and sand is derived primarily from eroded outcrops of the Kaibab and Moenkopi Formations that also supply dissolved calcite, gypsum, and minor amounts of salt that precipitates as cement. Pebbles, cobbles, and boulders are subangular to rounded limestone, chert, and sandstone clasts locally derived from bedrock. Also includes small, subrounded to rounded pebbles and cobbles of basalt, andesite clasts, and pyroclastic fragments derived from San Francisco Volcanic Field west and southwest of quadrangle. Supports light to moderate growths of sagebrush, cactus, and grass. North and northeast of Little Colorado River Valley (sheet 2): Gray, light-brown, and light-red clay, silt, sand, pebbles, and cobbles of chert, limestone, and sandstone; derived from local Mesozoic sedimentary rocks and monchiquite, basanite, and decomposed tuff from local outcrops of the volcanic rocks of Hopi Buttes Volcanic Field. Commonly is overlapped by or intertongues with various Quaternary surficial deposits (Qs, Qps, Qf, Qd, Qes, Qv, Qg1, Qae). Clay, silt, and sand are derived primarily from local outcrops of the Chinle, Moenave, Kayenta, and Bidahochi Formations; also derived from Cretaceous rocks north and northeast of quadrangle that commonly supply cementing ingredients of clay, calcite, gypsum, and minor amounts of salt for all surficial alluvial deposits north and northeast of Little Colorado River. Subject to extensive sheet-wash erosion, wind erosion, flash-flood debris flows, and minor arroyo erosion. Thickness, 1 to 6 m (3 to 20 ft)

ID: 2766775
Pliocene to late Miocene basaltic rocks

Age: Neogene (3.6 - 11.62 Ma)

Description: Mostly dark, inconspicuously flat, low-lying or mesa-forming basalt deposited as lava flows. Rocks included in this unit are located almost entirely in the large volcanic fields south and west of Flagstaff, in smaller fields in northwesternmost Arizona, and in the Hopi Buttes volcanic field on the Navajo and Hopi Indian Reservations north of Holbrook. Original volcanic landforms have been obscured by erosion. (4-8 Ma)
