BOWDISH SERIES <br />LOCATION BOWDISH CO+UT <br />Established Series <br />Rev. WSH-GB <br />08/97 <br />The Bowdish series consists of moderately deep, well drained soils that are formed in residuum derived <br />dominantly from sandstone and interbedded shale. Bowdish soils are on mesas, benches, ridges, and <br />escarpments and have slopes of 1 to 30 percent. The mean annual precipitation is about 13 inches and <br />the mean annual temperature is about 47 degrees F. <br />TAXONOMIC CLASS: Fine-loamy, mixed, superactive, mesic Ustic Haplocalcids <br />TYPICAL PEDON: Bowdish loam - pinon-Juniper woodland. (Colors are for airdry soil unless otherwise <br />noted.) <br />A--0 to 5 inches; brown (7.5YR 5/4) loam, dark brown (7.5YR 4/4) moist; weak medium subangular <br />blocky structure; slightly hard, very friable, nonsticky and slightly plastic; strongly effervescent; <br />moderately alkaline (pH 8.0); clear smooth boundary. (4 to 8 inches thick) <br />Bw--5 to 12 inches; light brown (7.5YR 6/4) loam, brown (7.5YR 5/4) moist; moderate medium <br />subangular blocky structure; hard, friable, nonsticky and nonplastic; lime disseminated throughout; <br />violently effervescent; moderately alkaline (pH 8.0); clear 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 <br />medium subangular blocky structure; hard, friable, nonsticky and slightly plastic; 15 percent pebbles; <br />lime disseminated throughout; violently effervescent; moderately alkaline (pH 8.2); abrupt wavy <br />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, <br />150 feet east 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 <br />lithic contact ranges from 20 to 40 inches. <br />The A and Bw horizons have hue of 7.5YR or 5YR, 4 to 6, 4 or 5 moist and chroma of 2 to 4. The rock <br />fragment content ranges from 0 to 30 percent, and is predominantly pebble and cobble sized. Reaction <br />is mildly alkaline or moderately alkaline. The Bk horizon has hue of 10YR through 2.5YR hue, 5 to 8, <br />(Revised June 2008) Attachment 2.04.9-3-18
