Orwood soils have more silt in the lower part of the B and C horizons. Razort soils tend to have a thinner solum and have less sand in the lower part of the B and C horizons, and are on gentler slopes. Renox soils have a thinner solum that contains more gravel throughout. Douds soils have an A horizon that is thinner or lighter colored or both. Mystic soils have a finer-textured Bt horizon of redder hue, and lower chroma and mottles are at shallower depths.
Caleb soils are on convex ridgetops and side slopes of high benches.
Their landscape configuration is partly related to valley fills, but the surfaces blend with the present erosional uplands. These areas are distinctly higher in elevation than the modern flood plains but are lower in elevation than the late Wisconsin dissection slopes on which the Gara, Shelby, and Lindley soils formed. Slope gradients range from 5 to 25 percent. Caleb soils formed in pre-Sangamon erosional sediments of variable texture and glacial origin. These materials appear to have been angularly truncated in many places, often resulting in an irregular mixture of material of contrasting textures.
