<br />c assif~ ad 5 a "variant" because the entire profile section is nonca lcareous. The ch roma of the Bw and Cg] horizons is one chip llgh ter than t he official
<br />series. The A horizon thickness is also one loch less than the required thick ness to be classifi ed as a mol l lc epipedon. All other pa ranee to rs are within the
<br />official range of charac tertst lcs. Assoc la ted vegetation at this sample site includes sagebrush, snowberry, and various grasses.

<br />Range of Characteristics: Routt was described at 11 locations within the study area (profile description site N6, 7, 10, 11, 15, 20, 23, 28, 29, 41, and 42).
<br />~e was c ass ie as a "variant" because the profile was somewhat poorly drained with high and low chroma mottles in the argillic horizon. The texture
<br />of the mollic epipedon ranges from fine sandy loam to silty clay loam. Reaction ranges from very strongly acid to neutral. All other parameters are within
<br />the official range of characteristics. Thickness of the mollic epipedon ranged from 18 to 29 inches with a mean of 22 inches. Coarse fragment content ranges
<br />up to 15 percent in some profiles. Dominant shrub vegetation at the description sites include oakbrush, snowberry, se rv iceberry, sagebrush, and chokecherry,
