Keya and Onita soils are in swales. Keya soils have a mollic epipedon more than 20 inches thick. Onita soils have a fine textured argillic horizon. Durrstein and Mosher soils have a natric horizon and are on similar landscapes. Runoff is low on nearly level areas to medium or high on the strongly sloping areas.
Permeability is moderate.
