An U occurrence located in the S½ sec. 24, T23N, R21E, G&SRM, 3.0 km (1.8 miles) SSW of Bidahochi Butte (coordinates of record) and 3.4 km (2.1 miles) S of Bidahochi. The geographic coordinates presented are for the center of sec. 24. This locality is not listed in the USGS MRDS database.

Mineralization is an U deposit hosted in Wingate Sandstone blocks in breccia overlying siltstone on the east edge of a diatreme. The ore body includes autunite.

Workings include surface openings comprised of a prospect pit.

Radioactivity is weak.

0 - 0.0117 Ma

ID: 3367262
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)

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)
