44 degrees 4 minutes 32 seconds north latitude and 107 degrees 13 minutes 26 seconds west longitude. The mollic epipedon is 16 to 60 inches thick. The control section is fine sandy loam or sandy loam and has 13 to 18 percent clay. Rock fragments, mainly less than 3 inches in diameter, range from 0 to 15 percent in the 10 to 40 inch particle size control section. This horizon is sandy loam or fine sandy loam.
Reaction ranges from slightly acid through slightly alkaline.
A Bw horizon is present in about half the pedons and has the same range as the A except dry value may be 6 and moist value may be 4. Reaction ranges from slightly acid through slightly alkaline. Aycab soils have a paralithic contact at depths of 24 to 40 inches. Cinderspring soils have a lithologic discontinuity consisting mostly of cinders. Earcree, Foxvire, Gardner's Fork, Hailman, and Razorba soils have over 15 percent rock fragments throughout the control section.
