Excerpt from Riverton Reclamation Project, Wyoming: Conservation Bulletin No. 24 The project lies entirely within an area of sedimentary formations. Strata underlying the soil consist of a soft sandstone and tightly compacted shale. As to origin the soil may be classed as residual, alluvial and lacustrine. A sandy soil of residual nature is usually found on the higher slopes. This grades to the heavier loams on the flatter slopes. Sandy loam to a clay loam of alluvial origin is found on the lower ground and in F ive - Mile and Muddy Creek valleys. The heavier soils usually carry a growth of a salt bush locally known as salt sage, a small plant with little root system which requires no extra work to eliminate. The lighter soil usually has ablack sage which may be broken loose with a steel rail as a drag, then raked and burned. Some of the soil contains a small amount of soluble white alkali but seldom enough to injure crops. Tracts which are thought to contain an excessive amount of alkali or are considered difficult to drain if they become seeped, and patches of light, sandy soil and rough, steep or rocky land are eliminated from the irrigable area.
