<br />Four soil types exist within the proposed permit area. These types are Cebone loam,
<br />Cimarron tome, Cumulic Cryaquolis, and Mayoworth clay loam.
<br />Descriptions of these four soil types from the Grand County Soil Survey by the U.S.
<br />Department of Agriculture can be found below:
<br />11-Cebone loam, 15 to 50 percent slopes. This
<br />moderately deep, well dreined, moderately steep to
<br />steep soil is on mountainsides at elevations of 7,500 to
<br />9,000 teat. It formed in residuum from shale and sand-
<br />stone. The average annual precipitation is about 16 to
<br />20 inches, the average annual air temperature is about
<br />36 to 41 degrees F, and the frost-free season is about
<br />30 to 80 days.
<br />Included in mapping are small areas of Cimarron loam,
<br />Mayoworth clay laflms, Anvik loam, end Lake Creek
<br />loam. Also Included are a few small arses of Cumulic
<br />Cryequolls, Cryoborolls, and Rock outcrop.
<br />Typically the surace layer of this Cebone soil is grey-
<br />ish brown loam about 11 inches thick. The subsurface
<br />layer is light gray loam about 5 Inches thick. The subsoil
<br />is yellowish Drown clay loam about 16 inches thick. The
<br />substratum is grayish brown clay. Soft, partially weath-
<br />eretl shale is et a depth of 36 inches.
<br />Permeability is slow. The effective rooting depth Is 20
<br />to 40 Inches. The available water Capflcay Is lbw. Sur-
<br />face runoff is rapid, end the erosion hazertl is high:
<br />Most of the acreage is rangeland. Pert of h is used for
<br />recreation end wildlife. Small areas have an overslory dt:
<br />quaking aspen. The cold climate end short growing
<br />season limit the producdon of InVOduced grasses end
<br />preclude the use of this soil as either cropland or wood-
<br />land.
<br />The rangeland vegetab'on is dominantly Thurber
<br />fescue and wheatgrass. As range condition detedorates,
<br />woody shrubs become dominant.
<br />Grazing management is nestled to maintain the condi-
<br />gon of this Biro. Pedodic deferment from grazing until the
<br />dominant grasses have produced seed will greatly im-
<br />prove plant vigor. Most of this site is too steep to be
<br />seedetl with a ddll.
<br />This soil provides food end cover for mule deer, elk,
<br />sage grouse, jackrabbtt, and coyote. W(Idlife can be in•
<br />creased if livestock grezirg is well managed.
<br />In stands of quaking aspen, this soil can produce 25 to
<br />35 cubic feet of wood per acre per year. The steep
<br />slopes make harvesting ddricuit
<br />The tlepth to rock, the high shrink-swell potential, end
<br />the slope ere the soil properties most limiting to wmmu-
<br />niry development. This soil is subject to hillside slippage
<br />it if becomes saturatetl. Road design should provide
<br />drainage outlets for surface runoff. Cut and fill slope
<br />should be kept to a minimum.
<br />The capability subclass is Vlle.
<br />18-Cimarron loam, 8 to 18 percent Hopp. This
<br />dpp, well drained, moderately sloping to strongly elop-
<br />ing Boll is on mountainsides entl tans at elevations of
<br />7,500 to 8,500 feet. It tormetl in local alluvium from
<br />shale. The averege annual precipitation is about 14 to 18
<br />Inches, the averege annual air temperature Is about 37
<br />to 42 degrees F, and frost-free season is about 35 to 75
<br />days.
<br />Includetl in mapping are small areas of Vouge loam,
<br />Cuender cobbty loam, Mayoworth clay loam, Woodhell
<br />loam, end Bentsen loam.
<br />Typically the surface layer of this Cimarron soil is dark
<br />grayish brown loam about 10 Inches thlok. The subsoil is
<br />grayish brown and pale brown clay about 22 inches
<br />thick. The substratum is light yellowish brown clay loam
<br />that extends to 60 inches or more.
<br />Permeability is slow. The effective rpoting depth is 60
<br />inches or more end me evallaDle water capacity is high.
<br />Surface runoff Is medium. The erosion hazard is motler-
<br />ate.
<br />Most of the acreage is rangeland (fig. 6). Part of h Is
<br />used for wiltlllfe and recreation. A smell acreage is ini-
<br />gated and Used for hay. The cold climate antl short
<br />growing season limit the production of inbotluced
<br />grasses and preclude the use of this soil es cropland.
<br />Wheatgrass, muttongrass, Idaho fescue, and big sage-
<br />brush ere the dominant species in the rangeland vegeta-
<br />iron.
<br />Grazing no more then 50 percent of the key species,
<br />by weight of the eurtent season producton, will maintain
<br />the condition of this site. Where shrubs have become
<br />dominant, brush comrol can improve range condigon. If
<br />the stte is in poor condhion, seeding is nestled. Adzona
<br />rescue, big bluegrass, slender wheatgrass, smooth
<br />brome, western wheatgress, end intermediate wheet-
<br />gress are sulreble for seetling. The seed should be
<br />tldlled into a fine seedbed.
<br />TNe soil provitlea winter range for mWe deer and elk.
<br />Other wildlife include sage grouse, jackrabbit, cottontail,
<br />end coyote. Managing livestxk grazing end controlling
<br />sagebrush are necessary to protect the big game winter
<br />range.
<br />The high shdnk-swell potental is the soil progeny
<br />most limiting to community development Slow perme-
<br />abiliry is also a limitation if this soil is used for septic
<br />tank absorption fields. Cut slopes, where necessary,
<br />should be designed to minimize potential soil slippage.
