<br />Rock outcrop cons~sts of exposed bare rock.
<br />
<br />Sediment yield from this association is 0,2-0.5 acre-feet/square
<br />
<br />mile/year, These soils are mainly used for range, recreation, subdivision,
<br />
<br />and irrigated cropland. General vegetative group is sagebrush-grass.
<br />
<br />Reclamation potential is good-poor, due to a combination of excess slope
<br />
<br />and coarse fragments, or rock outcrop.
