Fish Creek Soil Investigation <br /> <br />APPENDIX 3 <br />WINEVADA SERIES <br />The Winevada series consists of moderately deep, well drained soils formed in residuum and <br />colluvium derived from sandstone. Winevada soils are on mountain slopes and plateaus. Slopes <br />range from 3 to 70 percent. The mean annual precipitation is about 20 inches and the mean <br />annual temperature is about 38 degrees F. <br />TAXONOMIC CLASS: Fine-loamy, mixed, superactive Pachic Haplocryolls <br />TYPICAL PEDON: Winevada fine sandy loam, rangeland. (Colors are for dry soil unless <br />otherwise noted.) <br />Al--0 to 4 inches; very dazk grayish brown (lOYR 3/2) fine sandy loam, very dark brown (lOYR <br />2/2) moist; weak fine granulaz structure; soft, very friable, slightly sticky and slightly plastic; <br />slightly acid (pH 6.4); cleaz smooth boundary. (4 to 10 inches thick) <br />AZ--4 to 14 inches; very dazk grayish brown (1 OYR 3/Z) fine sandy Loam, very dazk brown <br />(1 OYR 2/2) moist; weak medium subangulaz blocky structure; soft, very friable, slightly sticky <br />and slightly plastic; neutral (pH 6.6); abrupt wavy boundary. (8 to 12 inches thick) <br />• A3--14 to 24 inches; dark brown (1 OYR 4/3) loam, very dark brown (1 OYR 2/2) moist; moderate <br />medium subangular blocky structure parting to moderate fine angulaz blocky; soft, friable, <br />slightly sticky and slightly plastic; neutral (pH 6.6); abrupt wavy boundary. (8 to 12 inches thick) <br />Cr--24 to 30 inches; fractured soft sandstone. (0 to 7 inches thick) <br />R--30 inches; fractured hazd sandstone. <br />TYPE LOCATION: Routt County, Colorado; approximately 8 miles southeast of Hayden, <br />about 400 feet north and 50 feet east of the southwest corner of Sec. 14, T. 5 N., R. 88 W.; <br />Latitude: 40 degrees, 23 minutes, 6 seconds N.; Longitude: 107 degrees, 14 minutes, 14 seconds <br />W. <br />RANGE IN CHARACTERISTICS: The mean annual soil temperature ranges from 39 to 44 <br />degrees F. and the mean summer soil temperature ranges from 56 to 59 degrees F. Depth to the <br />lithic contact is 20 to 40 inches. The Cr horizon is absent in some pedons. The particle-size <br />control section averages 18 to 27 percent clay, 15 to 35 percent silt, and 45 to 60 percent sand. It <br />is commonly a loam, sandy loam, or sandy clay loam. Content of rock fragments ranges from 0 to <br />30 percent. In some pedons, a thin layer immediately overlying the bedrock contains I S to 35 <br />percent rock fragments. The mollic epipedon is 16 to 30 inches thick. The soil is noncalcazeous <br />throughout. <br />The A horizons have a value of 3 or 4 dry, 2 or 3 moist, and chroma of 2 or 3. Reaction is neutral <br />or slightly acid. <br />Habitat Management, Inc. A3-15 01/06/04 <br />
