Depth to weathered shale ranges from 20 to 40 inches, and averages 35 inches. Tha celcic horizon has lass then 15% carbonates. All parameters except reaction, color, and depth to lime <br />are within the official range of characteristics. The A horizon value is 4 to 6 when tlry. The B horizon value is 4 to fi when dry antl the chrome is 2 to 4. Tha C horizon hue is 2.5Y or 5V, value is 3 to 7 dry antl 2.5 to 6 <br />moist, antl chrome is 1 to 4. Depth to visible lime ranges from 10 to 20 inches. Reaction is slightly acitl to motlerately alkaline. Clay content is 38 to 54% in the A horizon antl 43 to 74% in the B and C horizons. <br />Surface cracks ealentl to tlepths al 20 inches or more when the soils are dry. Dominant vegetation at the tlescription sites include low sagebrush, big sagebrush, western wheatgrass, slender wheatgrass, bluebunch <br />wheatgrass, squirreltail, and errowleaf balsemroot. <br />Aaberg Variant Ishallowl Inclusion in MU: 35C, 35D, 35E: SN: 58 Fine, mantmorillonitic, (rigid Udorthentic Chromusterts <br />A 0-2 CL 10YR5/2 10YR5/3 W F PL SO FR S/P Com VF,F O SE.
