' SD~LS EXHIBIT 1 f 1 1 l 1 r 1 Pondis Series The Fondis series consists of roll-drained soils Nat formed in soli an soil materials 1 to 2 feet Nick that overlie coarser textured outwash matarl- als derived from arkosic sedimentary rock. These gently sloping to steep soils are m uplands in Ne northern part of the Area. Slopes are 1 to 40 per cent. The vegetation is short and tall grasses. Elevations are 5,500 to 6,800 feet. Annual pxeipi- tation is 15 to 19 inches. Mean annual soil teaQsr- ature is 47' to SO' F., and Ne front-free seaam is 120 to 135 days. In • representative profile Ne surface layer, about 7 inches Viet, is dark grayish-brown clay loam. The upper part of the subsoil, about 21 inrhes Nick, is brown, grayish-brown, and light yellowish-brown clay. The lower part of Ne subsoil is very strongly calcareous sandy clay loam. The ~mderlying material is a buried soil Nat is brom and reddish-yellow sandy clay loam. It extends to a depN of 60 inches or mox, is very strongly ul- eaxous, and contains streaks of lir 2 to 6 inches ride. Fondis soils have slow permeability. Available rater capacity is high. Plants can penetrate to a depN of 60 inches or sore, except rhere bedrock is at a depN of about 40 inches or bela+. Most axes of Fondis soils ax in native grasses and used for grazing livestock. Game of Ne.less sloping areas an dryfarmed. Fondis ela loam Ito 3 ereent al es (FoB).-- This gently sloptng sotl is on tablelan and up- lands in the northern part of Ne Area. Most mapped areas are irregularly shaped and 20 to 100 acxs in size. Included with this soil in mapping ax small areas of Fondis clay loam, 3 to 9 percent slopes, [catch clay loam, 4 to 8 percent slopes, and Buick- gatanta looms, 3~to 9 percent slopes. Also included are small rock outcrops and • few lakes Nat fors /caring periods of intensive amounts of rainfall. Runoff is aKdian. The hazard of erosion is slight to moderate. A few gullies ax in drainage- rays. lost areas of this soil are cultivated and are used to grow wheat, barley, and oats. (Capability unit IIIc-1, dryland; lie-1, irrigated; Clayey Foothill range site) Fondis clay loam, 3 to ~rcent slopes (FOD).-- This sloping soil is on uplands zn t~~e northern part of the Area. Most mapped areas are irregularly shaped and range from 40 to 600 acres in size. Included with this soil in napping sx small areas of Kutch clay loam, 4 tc 8 percent slopes, Englerood clay loam, and Denver clay loam, 5 to 12 percent slopes. Also included are ^ few rock out- exops less Nan a quarter acre in size. Runoff is median. Thc hazard of erosion is aoder- ate. Gullies are on some of Ne larger drainagerays mot protected by grass. Most atess of this soil are cultivated and ax used to grow small grains, mainly wheat. A few axes ax in native pasture and are used for grazing 1lvestxk. (Capability unit Iva-3, dryland; IYe-1, irrigated; Clayey Foothill range site) Fondis-Kutch association (S to 40 pexent slopes) (Fu).--This association is about 50 percent Fondis loam and about 35 percent Kutch sandy loam. These strongly sloping to steep soils are on uplands in Ne northern part of the Area. In atypical area Ne Fondis soils are at higher elevations than the [catch soils. The Fondis soil has a profile similar to that de- scribed as representative for the series, but Ne surface layer, about 4 inches thick, is loam. Shale or sandstone is at a depth of 40 inches or more. The Newlin soil has a profile similar to that de- scribed as representative for the series, but it hu a surface layer of sandy loam 3 to 4 inches thick. Included with these soils in mapping are area of Newlin gravelly sandy loam, 8 to 30 percent slopes, ~ Bresser sandy loam, 3 to 9 percent slopes. Also included are a few small areas of Nilly gravelly land that are less than 5 acres in size and a few cliffs that are about 30 to 40 feet high. Taken together Nese areas make up about 15 percent of each napped area. Runoff is aedian to rapid. The emsion hazard is moderate to seven. In many places wall slips, or "catsteps," 6 to 12 inches high are present where slopes exceed 9 percent. Gullies and headcuts are present along drainageways. These areas are used for grazing livestock and for rildlife habitat. (Fondis soils: capability unit Vie-1; Loamy Foothill range site. Kutch soils: capability mit Yfe-1; Clayey Foothill range site) 1
