A former gypsum occurrence/mine located in secs. 15, 16 & 21, T19N, R15E, G&SRM, 0.3 km (0.2 mile) ENE of LeChee and 5.2 km (3.3 miles) WNW of Winslow, astride the Coconino County line along Interstate highway 40, on National Forest land.
Mineralization is a surface, sedimentary gypsum deposit. The ore body is 1.22 meters thick. Ore occurs irregularly and is hosted in Permian red sandstone and Late Triassic shale of the Moenkopi Formation, and is comprised of almost alabaster-like gypsum on surface and veinlets of satin spar with a slight greenish tinge. The gypsum beds are flat-lying and overlay red shale and underlie green shale. The deposit extends nearly 5 miles south from the railroad in a belt that is more than 1 mile wide in places. Produced during the period 1909-1914. Operated by the Acme Cement and Plaster Co. and the Navajo Gypsum and Fertilizer Co. The USGS MRDS database stated accuracy for this location is 2,000 meters. Local rocks include rocks of the Moenkopi Formation. NOTE: Deposit extends into Coconino County.
There was considerable production. The quarry is worked out. Material was shipped tom California for cement, plaster and agricultural use.
The grade and amount of resources remain unknown.
