<br />BOWDISH SERIES <br />LOCATION BOWDISH CO+UT <br />Established Series <br />Rev. WSH-GB <br />08/97 <br />The Bowdish series consists of moderatelydeep, well drained soils that are formed in residuum derived dominantly <br />from sandstone and interbedded shale. Bowdish soils are on mesas, benches, ridges, and escarpments and have <br />slopes of 1 to 30 percent. The mean annual precipitation is about 13 inches and the mean annual temperature is <br />about 47 degrees F. <br />TAXONOMIC CLASS: Fine-loamy, mixed, superadive, mesic Ustic Haplocalcids <br />TYPICAL PEDON: Bowdish loam - pinon-Juniper woodland. (Colors are for air dry soil unless otherwise noted.) <br />A-0 to 5 inches; brown (7.5YR 5/4) loam, dark brown (7.5YR 4/4) moist; weak medium subangular blocky sW cture; <br />slightly hard, very friable, nonsticky and slightly plastic; strongly effervescent; moderately alkaline (pH 8.0); Gear <br />smooth boundary. (4 to 8 inches thick) <br />• Bw-5 to 12 inches; light brown (7.5YR 614) loam, brown (7.5YR 5/4) moist; moderate medium subangular blocky <br />structure; hard, friable, nonsticky and nonelastic; lime disseminated throughout; violently effervescent; moderately <br />alkaline (pH 8.0); dear smooth boundary. (6 to 12 inches thick) <br />Bk-12 to 23 inches; pinkish white (7.5YR 8/2) gravelly loam, light brown (7.5YR 6/4) moist; weak medium . <br />subangular blocky structure; hard, friable, nonsticky and slightly plastic; 15 percent pebbles; lime disseminated <br />throughout; violently effervescent; moderately alkaline (pH 8.2); abrupt wavy boundary. (10 to 20 inches thick) <br />R-23 inches; hard sandstone. <br />TYPE LOCATION: Montrose County, Colorado, about 2.5 miles west and 3.5 miles north of Uravan,150 feet east <br />and 700 feet south of the northwest comer, sec. 18, T. 48 N., R. 17 W. <br />RANGE IN CHARACTERISTICS: Depth to the calcic horizon ranges from 5 to 20 inches. Depth to the lithic contact <br />ranges from 20 to 40 inches. <br />The A and Bw horizons have hue of 7.5YR or SYR, 4 to 6, 4 or 5 moist and chroma of 2 to 4. The rock fragment <br />content ranges from 0 to 30 percent, and is predominantly pebble and cobble sized. Reaction is mildly alkaline or <br />moderately alkaline. The Bk horizon has hue of 10YR through 2.5YR hue, 5 to 8, 3 to 6 moist, and chroma of 3 to <br />6. The texture is loam, sandy day loam, clay loam, or thin layers of sandy loam. The clay content is 18 to 35 <br />percent. The rock fragment content is 0 to 30 percent, and is predominanty pebble size. Reaction is moderately <br />alkaline or sVongly alkaline. The calcium carbonate equivalent ranges from 15 to 40 percent. COMPETING <br />• <br />(Revised March 2006) Attachment 2.04.9-3-15 <br />
