<br />The Satanta series consists of deep, well drained
<br />soils that formed in mixed alluvial and wind-deposited
<br />material. These soils are on uplands and high terraces.
<br />Elevation ranges from 4,800 to 6,600 feet. Slopes are
<br />0 to 9 percent. The native vegetation is mainly blue
<br />grams, buRalogress, western wheatgrasa, and cactus.
<br />Mean annual precipitation ranges from 13 to lb inches,
<br />mean annual air temperature ranges from 48° to 60°
<br />F, and the frost-free season ranges from 136 to 160
<br />days.
<br />In a representative profile the surface layer is dark
<br />grayish brown loam about 7 inches thick. The subsoil
<br />is brown clay loam and pale brown loam about 16
<br />inches thick. The underlying material ie very pale
<br />brown loam about 21 inches thick over very pale brown
<br />fine sandy loam.
<br />Permeability ie moderate, and the available water
<br />capacity is high. Reaction ie mildly alkaline above a
<br />depth of 18 inches and moderately alkaline below that
<br />depth.
<br />These soils are used mainly for irrigated and dry-
<br />farmed crops and for pasture.
