An U occurrence probably located in sec. 23 (Bobcat Butte), or the NW¼ sec. 14 and SW¼ sec. 11 (Saddle Butte), T24N, R15E, G&SRM, approximately 12.7 km (7.9 miles) ENE of Tolani Lake, on the NE side of the butte. The geographic coordinates presented are for the common corner (SW sec. 11 - NW sec. 14).
Mineralization is collapse sediments of the Bidahochi Formation associated
with a diatreme. Mineralized travertine beds form the dip slope.

| Holocene 0 - 0.0117 Ma ID: 3376250 | Eolian sand-sheet deposits Age: Anthropocene (0 - 0.0117 Ma) Description: Extensive sand-sheet deposits northeast and east of Little Colorado River Valley, especially in and along large tributary washes and over gently sloping terrain below Newberry, Ives, and Marcou Mesas. Forms thin sand-sheet deposits on alluvial fan slopes of various ages and on “Dilkon deposits” (QTdi) slopes in Hopi Buttes area. Commonly intertongues with surficial deposits (Qae, Qdp, Qdb); contacts are gradational in both lateral and vertical sense. Supports moderate growths of grass and small high-desert shrubs that help stabilize or trap accumulating deposits.

| Toarcian - Norian 174.1 - 227 Ma ID: 2976883 | 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.
