Hall and Hord soils contain less clay, do not have a natric horizon, and free calcium carbonates are deeper. Lamo and Leshara soils do not have a natric horizon, are fine-silty, and Lamo soils have a thicker mollic epipedon. Rusco soils lack a natric horizon and are fine-silty. These soils are somewhat poorly drained. Runoff is low.
Permeability is slow in the upper part and moderately rapid or rapid in the lower part.
