' Official Series Description - &KARD Series • Page 2 of 2 <br /> COMPETING SERIES: These are the Draknab (WY), Ellicott(CO), Escavada(NM), and Kwakina <br /> (T)(NM) series. Draknab soils are never moist in some or all parts for as long as 60 consecutive days <br /> when the soil at 20 inches is 41 degrees or more. Ellicott soils are noncalcareous and contain a high <br /> ' proportion of medium and coarse angular granite sand and fine and very fine angular granite gravel. <br /> Escavada and Kwakina soils are driest from April through June. <br /> ' GEOGRAPHIC SETTING: These soils are on flood plains and low terraces. Slope gradients range <br /> from 0 to about 6 percent. The soils formed in calcareous highly stratified but predominantly coarse <br /> textured recent alluvium derived from a variety of rocks. At the type location, the average annual <br /> ' temperature ranges from 48 to 55 degrees F., the average summer temperature is 70 degrees F., and <br /> the average annual precipitation is 10 to 17 inches with peak periods of precipitation in the spring <br /> and early summer. <br /> GEOGRAPHICALLY ASSOCIATED SOILS: These are the Glenberg and Haverson soils. <br /> Glenberg soils have a coarse-loamy control section. Haverson soils have a fine-loamy control section. <br /> 1 DRAINAGE AND PERMEABILITY: Well to somewhat excessively drained; low or very low <br /> runoff-, rapid or very rapid permeability. <br /> ' USE AND VEGETATION: These soils are used chiefly as native pastureland; however,they are <br /> tilled in some localities. Native vegetation consists of scattered cottonwood, grass, and brush. <br /> ' DISTRIBUTION AND EXTENT: The flood plains and low terraces of the major streams in <br /> Colorado,Kansas, Wyoming, New Mexico, and parts of South Dakota, Nebraska, and eastern Utah. <br /> MLRA OFFICE RESPONSIBLE: Salina,Kansas <br /> SERIES ESTABLISHED: Red Willow County,Nebraska, 1965. <br /> REMARKS: Last updated by the state 2/94. <br /> National Cooperative Soil-Survey- <br /> U.S.A. <br /> t <br /> 1 <br />
