Potash-bearing rocks of the Leucite Hills, Sweetwater County, Wyoming

The purpose of the present paper is to give a brief description of the rocks in the Leucite Hills, Wyo., with an estimate of the amount of leucite-bearing rock available and of the approximate amount of potash that these rocks may yield as soon as a process is discovered by which the potash may be dissociated from the rock cheaply enough for commercial use.
