<br />contact at 20 to 40 inches. Pokeman soils have alabaster at 20 to 40 inches and hues redder than 7.SYR
<br />throughout. Pugsley and Spangler soils are noncalcareous throughout.
<br />GEOGRAPHIC SETTING: Bowbac soils are on dissected fan remnants, fan piedmonts, hillslopes, pediments,
<br />ridges and buttes. Slopes are 0 to 15 percent. Elevations are 3,500 to 6,500 feet. The average annual precipitation
<br />is 13 inches with over half of the annual precipitation falling in April, May, and June and less than one inch falling
<br />in each month of July, August, September, and October. Precipitation ranges from 10 to 14 inches. The mean
<br />annual temperature ranges from 43 to 51 degrees F. The frost-free season is about 110 to 130 days.
<br />GEOGRAPHICALLY ASSOCIATED SOILS: These are the competing Cushman, Hiland, and Cambria soils and
<br />the Pannleed soils. Parmleed soils have over 35 percent day in the Bt horizon.
<br />DRAINAGE AND PERMEABILTfY: Well drained; runoff is medium or low, moderate permeability.
<br />• SE AND VEGETATION: These soils are used primarily for grazing. Native vegetation is needleandthread grass,
<br />blue grams, western wheatgrass, and big sagebrush.
<br />DISTRIBUTION AND EXTENT: CenUal and northern Wyoming. The soil is extensive.
