GEOGRAPHICALLY ASSOCIATED SOILS: These are the Blacknoll, Jacoby (T), Katseanes, Nayrib, Pinebutte, Eaglecone (T), Stipe, Vadnais, Wolverine and the competing Stipe series soils. Blacknoll and Vadnais soils are moderately deep. Jacoby have mollic colors less than 50 cm thick. Katseanes soils are shallow. Nayrib soils are on pressure ridges and are very shallow. Pinebutte soils are fine-loamy. Eaglecone soils have greater than 35 percent coarse fragments in the control section. Wolverine soils are on stabilized dunes and lack a mollic epipedon and calcic horizon.
