Diagnostic horizons and features recognized in this pedon are:
Particle size control section: 29 to 79 cm (11 to 31 in) (Btnz, Btnzy1, and Btnzy2 horizon)
Ochric epipedon: 0 to 29 cm (0 to 11 in. (A1 and A2 horizons)
Natric horizon: 29 to 203 cm (11 to 80 in) (Btnz, Btnzy1, Btnzy2, Btnzy3, and Btnyg horizons)
Aquic conditions: 15 to 46 cm (6 to 18 in) (Btnz, Btnzy1
