• <br />SOILS DESCRIPTION <br />ADAMS COUNTY, COLORADO <br /> SANDY ALLUVIAL LAND (Sm) consists of an unstable accumulation of <br />~ gravelly and sandy alluvium. It is in and adjacent to beds of <br /> intermittent streams throughout the eastern three-fourths of Adams <br /> County. During periods of heavy rain, the streambeds are subject to <br /> flooding, and channels are relocated and sediment is shifted and <br /> redeposited at slightly different locations. During dry spells, this <br /> land type is extremely droughty. <br /> Sandy alluvial land consists of material that was transported by <br />~ water from the sand and gravel beds in or adjacent to the area. It is <br /> stratified because of periodic flooding. Thin lenses or small pockets <br /> of silt, clay, and sand are also mixed with the gravel. <br /> This land type differs from Wet alluvial land primarily in that <br /> it is coarser textured throughout and is not affected by a water <br /> table. <br />~ Sandy alluvial land is either barren or has only a sparse cover <br /> of weeds. It is used for grazing along with' the better rang?land <br /> adjacent to it. Capability unit VIIw-1, nonirrigated; not placed in a <br /> range site; tree planting suitability group 4. <br />~~ <br />~~ <br />~~ <br />~~ <br />I~ SOIL SURVEY OF ADAMS COUNTY, COLORADO; USDA, Saii Conservation <br />Service in cooperation mith Colorado ASricultural fsperimeht Station, <br />October 1974. <br />~~ <br />~~ <br />
