Bt horizons and very gravelly loamy sand BC horizons. Elliber soils average more than 50 percent rock fragments and less than 27 percent clay in the top 20 inches of the Bt horizon. Gainesboro, Hartleton, and Irondale have sola less than 40 inches thick. Lew soils contain fragments of greenstone. Pattenburg soils have hue of 2.5YR or redder.
Mertz soils occupy the gently sloping to steep upper and middle parts of chert ridges.
Slope gradients range from about 3 to 35 percent. They formed in loamy cherty colluvium or glacial influenced material derived from limestone containing varying chert fragments. The climate is temperate and humid. Mean annual air temperature ranges from 47 to 57 degrees F., mean annual precipitation ranges from 36 to 48 inches, and the frost free season ranges from 150 to 210 days. These are the competing Elliber soils and the Evendale , Hagerstown , Kraemer, Morrison , and Vanderlip soils.
