The Basin is divided on the general soil map among 9 units that have
been delineated as described above. Separations between units are
generalized in accordance with requirements imposed by the map scale.
Acreage distribution of units and percent each occupies is given in
table 3. Soil mapping units delineated on the general soil map are
described on the following pages.

White River Basin in Colorado.

Soil Mapping Unit 1: Shallow and deep, light colored shale soils of
the deserts.

Soils of this unit are located in two areas on the general soil map.
One is the desert basin near Rangely and the other extends from near
Elk Springs westerly to the Utah State line. These have a total area
of l18,000 acres or a little less than 5 percent of the Basin.

The landscape is characterized by rolling shale hills broken by narrow,
gently sloping strips of alluvial soils bordering drainageways and
colluvial slopes. Slope gradients are chiefly in the 5 to 25 percent
range but there are portions with less than 5 percent. Larger areas
where slopes are from 0 to 5 percent are along waterways or on bottom-
lands and terraces bordering the White River and its tributaries. Very
steep shale badlands and escarpments border the boundaries of this mapping
unit at many places and are particularly noticeable north and west of
Range1y.
