Aycock and Blevins soils are siliceous and formed in marine sediments. Bewleyville and Mountview soils are siliceous and have discontinuties of residuum weathered from limestone below the silty mantle. Crider soils have base saturation of more than 35 percent and are mesic. Curtistown soils are siliceous and have surface layers with a value less than 4. Etowah and Minvale soils are fine-loamy.
Pickwick soils are on old, high terraces of major streams and rivers.
The topography is gently sloping to hilly. Slopes range from 2 to 20 percent. The soil formed in a silty mantle 1 to 3 feet thick over old alluvium or entirely in old alluvium. At the type location the average annual precipitation is about 55 inches, and the average annual temperature is about 62 degrees. These are the similar Bewleyville , Etowah , Minvale , and Mountview series, and the Paden , Waynesboro , and Wolftever series.
