<br />SOtL SURVEY
<br />Use o1 this soil for community development, for sani-
<br />tary facilities, and as a source of construction material is
<br />li.mded by steep slope:., birth clay content, low strength,
<br />depth to bedrock and shnnk~swell potential. Road con-
<br />struction and bwlding foundations can be designed to
<br />reduce the effects of shrinking and swelling. A good
<br />drainage system reduces soil slumpiny.
<br />This soil is in capability subclass Vlle, nonirrrgated.
<br />Aw
<br />65-Torrifluvents, nearly level. This broadly defined
<br />unit consists of deep„well drained to somewhat poorly
<br />drained, nearly fevEl soils on flood plains adjacent to the
<br />Colorado and Roaring Fork Rivers and their major tribu-
<br />taries. Slope ~s 0 to 6 percent. The soils formed in
<br />alluvium.
<br />These soils are stratified and vary widely in texture
<br />and depth. The surface layer ranges from loamy sand
<br />and fine sandy loam to silly loam and clay loam. The
<br />underlying layers are generally sandy loam or loam strati-
<br />fied with sand, gravel, and cobbles. In some areas gravel
<br />and cobbles are on or near the surface.
<br />The water table fluctuates between depths of 2 and 4
<br />feet and in some years is near the surface during spring'
<br />runoff from snc::~^rel!. These SCllc gre ci~bicrt to Vjr~o1
<br />occasional flooding late in spring and early in summer.
<br />Included'in mapping are small isolated areas of Wann
<br />soils that have slopes of 1 to 3 percent. Small areas of
<br />soils that are moderately to severely affected by alkali
<br />are identified by an alkali spot symbol. Small, isolated
<br />areas where water stands at or near the surface all year
<br />are identified by wet spot and marsh spot symbols.
<br />These areas make up 15 percent of the map unit.
<br />These soils are used for wildlife habitat, recreation,
<br />and some grazing.
<br />The native vegetation is mainly cottonwood, willow,
<br />tamarisk and water-tolerant grasses, sedges, and rushes.
<br />In many areas these soils are suited to production of
<br />Fremont cottonwood. The soils are capable of producing
<br />230 board feet of timber per acre from a fully stocked,
<br />even-aged stand of 40-year-old trees.
<br />Where these soils are accessible, they provide shelter
<br />and forage for livestock.
<br />Mule deer, cottontail rabbit, coyote, bobcat, ducks,
<br />geese, and other native buds find food and shelter on
<br />these soils. Where feasible, planting food plots, trees
<br />and shrubs, and nesting cover enhances the habitat for
<br />upland wildlife. Where the water table is high, open
<br />water for waterfowl and fish can be developed by blast-
<br />ing or by excavating.
<br />These Soils have potential for recreation. Wildlife is
<br />abundant, and the nearby rivers can be used for rafting
<br />and canoeing. Community development is very limited by
<br />flooding, the seasonal high water table, and variable
<br />texture. Onsite investigation is necessary.
<br />These sods are in capability subclass Vllw, nonirrigat-
<br />ed.
