<br />The Bowdish series consists of moderately deep, well drained soils that are farmed
<br />in residuum derived dominantly from sandstone and interbedded shale, Bowdish
<br />soils are on mesas, benches, ridges, and escarpments and have slopes of 1 to 30
<br />percent. The mean annual precipitation is about 13 inches and the mean annual
<br />temperature is about 47 degrees F.
<br />TAXONOMIC CLASS: Fine - loamy, mixed, superactive, mesic Ustic
<br />Haplocaicids
<br />TYPICAL PEDON: Bowdish loam - pinon- Juniper woodland. {Colors are for air
<br />dry soil unless otherwise noted.)
<br />A to 5 inches; Drown (7.5YR 514) loam, dark brawn (7.5YR 4/4) moist; weak
<br />medium subangular blocky structure; slightly hard, very friable, nonsticky and slightly
<br />plastic; strongly effervescent: moderately alkaline (pH 8_0); clear smooth boundary.
<br />(4 to 8 inches thick)
<br />13w- -5 to 12 inches; light brawn (7.5YR 6/4) loam, brawn (7.5YR 514) moist;.
<br />moderate medium subarlgular blocky structure; hard, friable, nonsticky and
<br />nonplastic; lime disseminated throughout; violently effervescent; moderately alkaline
<br />(pH 8_D); clear srneoth boundary. (8 to 12 inches thick)
<br />Bk ° to 23 inches; pinkish white (7.5YR 8/2) gravelly loam, light brown (7.5YR
<br />6/4) moist; weak medium subangulair blocky structure; hard, friable, nonsticky and
<br />slightly plastic; 15 percent pebbles; lime disseminated throughout; violently
<br />effervescent; moderately alkaline (pH 8.2): abrupt wavy boundary. (10 to 20 inches
<br />thick)
<br />R --23 inches; hard sandstone.
<br />TYPE LOCATION: Montrose County, Colorado, about 2.5 miles west and 3.5
<br />miles north of Uraven, 150 feet east and 700 feet south of the northwest corner, sec.
<br />18, T. 48 N., R. 17 VV.
<br />RANGE IN CHARACTERISTICS: Depth to the calcic horizon ranges from 5 to
<br />20 inches. Depth to the 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
<br />chrorna of 2 to 4. The rack fragment content ranges from 0 to 30 percent, and is
<br />predominantly pebble and cobble sized. Reaction is mildly alkaline or moderately
<br />alkaline. The Sk horizon has hue of 10YR through 2.5YR hue, 5 to 8, 3 to 6 moist,
<br />and chroma of 3 to 6. The texture is loam, sandy clay loam, clay loam, or thin layers
<br />of sandy loam. The clay content is 18 to 35 percent. The rock fragment content is 0
<br />to 30 percent, and is predominantly pebble size. Reaction is moderately alkaline or
<br />strongly alkaline. The calcium carbonate equivalent ranges from 15 to 40 percent.
<br />COMPETING SERIES These are the Abra, Bigharns, Cibeque, Copeman, Creel,
<br />Darvey, Harvey, Hernandez, Honlu, Numa, and Pultney series. } bra, Cibeque,
<br />Garvey, Harvey, Fernandez, Honlu, and Nurna soils are deep. Pultney soils have
<br />10YR and yellower hues and have 10 to 15 percent exchangeable sodium in the Cky
<br />horizon. Bighams soils have a paralithic contact at 20 to 40 inches. Creel soils have
