REMARKS:
In the past, Yeopim soils have been included with Dogue and Altavista soils. However, Dogue soils are in a clayey family and Altavista soils are in a fine-loamy family. Particle size data is available for this pedon.
Diagnostic horizons and features recognized in this pedon are:
Ochric epipedon--the zone from the surface to a depth of 8 inches (the Ap horizon)
Argillic horizon--the zone from a depth of 8 inches to a depth of 42 inches (the Bt1, Bt2 and Bt3 horizons)
