SECTION G - SOILS AND VEGETATION <br />Soils <br />-ames A. Crabb, Soil Scientist with the U. S. Soil <br />Conservation Service, 2017-9th Street, Greeley, Colorado <br />80631, in a communication to Burman Lorenson, Weld County <br />Planning Department, on February 14, 1974, stated as follows: <br />"The soils in this area (230 acres located in parts of NE4, <br />Section 9, and NW4, WhNE4, Section 10, Township 5 North, <br />Range 65 West, Weld County, Colorado) are shallow to moderately <br />deep (10 to 40 inches) to sand and gravel, and being on the <br />Flood Plain of the Cache La Poudre River have a shallow <br />water table and are subject to flooding. The area-is bi- <br />sected by old channels of the Poudre River and several <br />gravel pits. This area is probably better suited for <br />commercial sand and gravel then for agriculture, however <br />there is always the hazard of pollution to the Poudre River <br />from extraction process." <br />Soils with the above stated capabilities are usually <br />not suitable for usual crop production cultivation and thus <br />their use is mainly restricted to pasture, woodland or <br />wildlife. More specifically, the following is a complete <br />description of the soils within proposed mining areas as <br />provided by the U.S. Soil Conservation Service: <br />3 - Aquolls and Agents, gravelly substratum <br />These nearly level soils are on bottom lands and flood <br />plains of all the major streams in the survey area. The <br />Aquolls, which have dark colored surface layers, make up <br />about 65 percent of the mapping unit. The Aquents, which <br />have lighter colored surface layers:, make up about 25 per- <br />cent. About 10 percent is Aquolls:'and Aquepts, flooded, <br />and Bankard sandy loam. <br />These are deep, poorly drained soils, They formed in <br />recent alluvium. Typically they have mottled, mildly <br />to moderately alkaline, loamy or clayey surface layers <br />and underlying material, and are underlain by sand or <br />sand and gravel within 48 inches. They may or may not <br />have a gleyed layer in the underlying material. <br />Most of these soils are subject to flooding. A water-, <br />table is at or near the surface early in the spring and <br />recedes to as deep as 48 inches by late fall in some <br />years. <br />-7-
