<br /> <br /> <br /> Coni Series <br /> The Coni series consists of shallow, well-drained <br /> soils that formed in arkosic sedimentary rock over- <br /> lying unweathered conglomerate. These gently slop- <br /> ing to sloping soils are at or near the edge of <br />' tablelands in the southern part of the Area. Slopes <br />are } to 15 percent. The vegetation is dominantly <br /> short and mid grasses, but in places there are pine <br /> trees and btvsh, Elevations are 6,600 to 7,800 <br /> feet. Annual precipitation is 17 to 21 inches. <br />lkan annual soil temperature is 4}• to 47' F., and <br /> the frost-free season is 115 to 125 days. <br /> In a representative profile the surface layer, <br /> about 7 inches thick, is dark grayish-brown loam. <br /> The subsoil, about ]0 inches thick, is a brown to <br /> pale-brown clay loam to sandy clay loam that rests <br /> on hard conglomerate at a depth of 17 inches or <br /> less. <br /> Loni soils have moderate permeability. Available <br /> rater capacity is low. Plants tan penetrate to a <br /> depth of 20 inches or less. <br /> Ibsi ere as of Coni soils are in native grasses <br /> and are used for grazing livestock and for wildlife <br />habitat. <br /> <br /> Coni rocky loam, 3 to 100 percent slopes (CoG).-- <br /> This complex is about 70 percent Coni loam and about . <br />' 13 percent Roek outcrop. This complex is on or near <br /> tableland edges in the southern part of the Area. <br /> It is made up of long, narrw bands about 1,000 feet <br /> or less in width and extending for several miles in <br /> length. In most places these areas are more than <br /> 100 acres fn size. In a typical area of this com- <br /> plex Coni loam has slopes of 3 to 15 percent; the <br /> Rock outcrop is mainly near nearly vertical cliffs <br /> (plate IV, right). <br /> Included in mapping are areas of 8nsssett loam, <br /> 3 to 9 percent slopes, Kettle sandy losm, Stony <br /> rough land, and Kettle and Falcon soils. Taken <br /> together these areas sake up 15 percent of each <br />' tapped area. <br /> Surface runoff is rapid. fie hazard of water <br /> erosion is moderate to severe, especially in the <br /> spring during-snowmeit. <br /> lost areas of this complex are used for grazing <br /> livestock. The panoramic view from areas of this <br /> eomplei sake it a popular site for homes. (Capa- <br /> bility tacit VIIe-]; Loamy Park range site) <br /> <br /> <br /> <br />
