Choates,
Shankler,
Newco,
Hillister series.
Letney, Tehran, Doucette, Boykin, and Shankler soils: have a loamy argillic horizon.
Choates soils: on toe slope positions, and have a seasonal water table
at 1.5 to 2.5 feet.
Hillister: are on side slopes and have a loamy argillic horizon. Newco soils: are on side slopes and have a clayey argillic horizon.
