HOWARDSVILLE The Howardsville series consists of very deep, somewhat excessively drained soils that formed in alluvium derived mainly from rhyolite, tuff, and similar volcanic rocks. Howardsville soils are on fan remnants and river terraces. Slopes range from 1 to 6 percent. Mean annual precipitation is about 25 inches and the mean annual temperature is about 35 degrees F. Taxonomic class: Sandy-skeletal, mixed Ustic Haplocryepts Reference Pedon: Howardsville gravelly loam, on a west facing, simple, 1 percent slope in grassland at an elevation of 9,300 feet. (Colors are for dry soil unless otherwise noted.)When described on August 2, 1983 the soil was slightly moist from 0 to 10 inches. A-- 0 to 2 inches; dark grayish brown (10YR 4/2) gravelly loam, black (10YR 2/1) moist; moderate fine granular structure; soft, friable, nonsticky and nonplastic; 15 percent gravel, 5 percent cobbles; slightly acid (pH 6.2); clear smooth boundary. (2 to 6 inches thick) Bw--2 to 10 inches; brown (7.5YR 5/4) very gravelly sandy loam, dark brown 7.5YR 3/4) moist; weak fine granular structure, soft, friable, nonsticky and nonplastic; 30 percent gravel, 10 percent cobbles, and 2 percent stones; moderately acid (pH 6.0); clear wavy boundary. (6 to 20 inches thick) C--10 to 60 inches; light brown (7.5YR 6/4) extremely cobbly loamy sand, dark yellowish brown (10YR 4/4) moist; single grain; loose, nonsticky and nonplastic; 30 percent gravel, 25 percent cobble, and 10 percent stone; moderately acid (pH 5.8).
