Pg. 76, 82. Bechler conglomerate of Gannett group. Gray, reddish, and "salt and pepper" sandstones with interbedded conglomerates. Pebbles of conglomerate are small, few having diameter of more than 1 inch. Thickness 1,776 feet. Underlies Draney limestone and overlies Peterson limestone; all in Gannett group. May be Jurassic. [ca. 1936, age is considered Cretaceous(?).]

Is one of five formations in the Gannett Group. Overlies Peterson Limestone of the Gannett. Underlies Draney Limestone of Gannett. Cross sections. Isopach map; thickens westward from less than 200 ft thick in western Lincoln Co, WY (Greater Green River basin) to 1600+ ft thick in Caribou Co, ID (Wasatch uplift). Extends northward into Bonneville Co, ID (Snake River basin) and southward into Bear Lake Co, ID (Wasatch uplift). Exposures along Bechler Creek considered to be the type section where it consists of conglomerate, sandstone, and mudstone. Calcareous nodules present in mudstone. Measured section in Lincoln Co described where Bechler is 1,113.5 ft thick. Probably is an orogenic deposit. Microfossils found in nodular zones. Fossils (charophytes, ostracods) listed. Of Early Cretaceous, Aptian age.
