REMARKS: This soil was previously mapped as Tatum, a thermic soil.
Diagnostic horizons and features recognized in this pedon:
1. Ochric epipedon-zone from the surface to 8 inches (A and E horizons)
2. Argillic horizon-zone from 8 to 41 inches (Bt horizon)
3. Paralithic contact-starting at 41 inches
ADDITIONAL DATA: Ranges for morphology, chemistry, particle size distribution, and mineralogy are based on 3 pedons and the thermic counterpart to this soil.
