Geographically Associated Soils
Allen soils, which have B horizons with a hue of 5YR or redder
Nauvoo soils, which have B horizons with a hue of 5YR or redder and have
sandstone bedrock at a depth of 40 to 60 inches

percent rock fragments throughout the profile
Sequatchie soils, which are on the slightly lower landscapes, have an umbric
epipedon, and have a solum less than 60 inches thick
