TAXONOMIC CLASS: Mixed, mesic Aridic Ustipsamments
TYPICAL PEDON: Dankworth loamy sand on a 5 percent north facing slope in rangeland. When described, the soil was moist throughout. (Colors are for dry soil unless otherwise stated.)
A--0 to 6 inches; grayish brown (10YR 5/2) loamy sand, dark grayish brown (10YR 4/2) moist; weak fine granular structure; soft, very friable; 2 percent gravel by volume; slightly acid; clear smooth boundary.
AC--6 to 18 inches; grayish brown (10YR 5/2) sand, dark brown (10YR 3/3) moist; single grain; loose; 2 percent gravel by volume; slightly acid; clear smooth boundary.
C1--18 to 48 inches; pale brown (10YR 6/3) coarse sand, brown (10YR 5/3) moist; single grain; loose; 13 percent gravel by volume; slightly acid; gradual smooth boundary.
C2--48 to 80 inches; light gray (10YR 7/2) sand, light brownish gray (10YR 6/2) moist; single grain; loose; 2 percent gravel by volume; slightly acid.
TYPE LOCATION: Garden County, Nebraska; about 8 miles north and 5.5 miles east of Oshkosh Nebraska; 1900 feet north and 800 feet west of the southeast corner of section 23, T. 18 N., R. 43 W.
