Dry Screening manganese ore fragments from the soil at the C.F.I. mine, southeast of Green River.

In places these fragments rather closely pave the surface, generally they are mixed with a foot, more or less, of loose sandy soil. These ore fragments were originally parts of a thin horizontal bed of manganese oxides. Lowering of the surface by erosion, in which wind deflation has played a large part, exposed the manganiferous layer that became broken into fragments but was not comminuted sufficiently to be removed by the wind. As the more friable sandstone that adjoins...
