These are the Muldrow and Santee series in the same family. Muldrow soils are noncalcareous throughout and have less than 30 percent sand in the upper 20 inches of the control section. Santee soils lack calcium carbonate concretions in the lower part of the argillic horizon and are moist for longer periods of time. Slopes are 0 to 1 percent. They formed in alluvium or aeolian sediments of Pleistocene age.
