Slope gradient ranges from 2 to 14 percent. The soils formed in 24 to 40 inches of loess and the underlying loamy residuum weathered from sandstone. The mean annual temperature ranges from 54 to 57 degrees F, and the mean annual precipitation ranges from 40 to 45 inches. These are the competing Menfro and Weingarten soils and the Gasconade , Goss , Holstein , Lily , and Ramsey soils. Menfro soils occupy ridgetops or foot slopes where the loess is thicker.
Weingarten soils are on similar positions.
Gasconade, Lily, and Ramsey soils have bedrock at depths less than 40 inches and are on lower side slopes. Goss soils have cherty clayey subsoils and are on lower side slopes. Holstein soils are fine-loamy and are on lower side slopes. Well and moderately well drained. Runoff is medium or rapid.
