The Arenzville, Chaseburg, and Eitzen soils are in narrow drainageways below the Yellowriver soils. The Fayette and Southridge soils are on less sloping ridgetops and side slopes above the Yellowriver soils. Boone and Lacrescent soils are on steeper side slopes above the Waterville soils. The Churchtown soils form a biosequence with the Yellowriver soils and are on similar landscape positions. Permeability is moderate.
Surface runoff is medium to very rapid.
The less-sloping areas are commonly used to grow corn, small grain, and legume hay. The steeper slopes are used for pasture. Native vegetation was deciduous trees. The series is moderately extensive. Allamakee County, Iowa, 1989.
