<br /> <br />;TOIL MAPPING UAi ITS <br />-Cragola and Cragola, moderately deep Variant soil:;, 30 to 40 percent slopes. <br />These soils fit the concept; of the Cragola series, ercept that Cragola soils are <br />less than 20 inches deep to bedrock. Uepth to tedroc}: in this unit is about ]5 <br />to 30 inches. The soils profiles where depth to bedrock is greater than 20 inches <br />are moderately deep variani.s of tt,e CY~agola series. The shallow and moderately <br />deep soils occur in a comp]ex pattern. Permeability is moderate, The average <br />annual precipitation is about 13 Snches. <br />The following are descriptions of the profiles sampled at points 1 and 2 on Attach- <br />ment Ci <br />• {11 Cragola, moderately deep Variant <br />Al--0 to 4 inches; light brown (~,SYR 6/4) stony loam, brown (7.5 YR 4/4) <br />moist; weak fine granular structure; soft, very friable, slightly sticky and non- <br />plastic; 25 percent gravel, 5 percent cobbles, 1 percent stones; violently effer- <br />vescent; moderately alkaline (pH 8,2); gradual smooth boundary. <br />Cca--4 to 24 inches; light brown (~.SYR 6~4) very gravelly loam, brown (7,5 YR <br />4/4) moist; weak medium subangular blocky structure; slightly hard, friable, slightly <br />sticky and slightly plastic; 30 percent gravel, 10 percent cobbles; violently effer- <br />vescent; moderately alkaline (pH 8.4 ); abrupt irregular boundary, <br />Cr--24 inches; sandstone. <br />~/2 Cragola <br />Al--0 to 4 inches; light brown (7.5 YR 6/4) stony sandy clay loam, brown (9.5 YR <br />5/3) moist; weak fine granular structure; soft, friable, slightly sticky and nonplastlc; <br />30 percent gravel, 15 percent cobbles, 10 percent stones; strongly effervescent; mod- <br />erately alkaline (pH 8,2 ); ~olear smooth boundary. <br />• Cca--4 to E9 inches; light brown (7.5 YR 6/4) extremely gravelly loam, brown <br />(7,5 YR 5/4) moist; xeak medium subangular blocky structure; hard= friable; sticky <br />and slightly plastic; 50 pe:ccent gravel, 15 percent cobbles, 2 percent stones; <br />• violently effervescent; mod~arately alkaline (pH 8,4 ); abrupt irregular boundary. <br />Cr--19 to 24 inches; so:Ft sandstone. <br />G--Gypsum Iand <br />This is outcrops of gypsum rock or decomposed bypsum rock.
