These soils formed in 30 to 50 inches of loess and Late Sangamon paleosols formed in sandy loam, loam or clay loam Illinoian till. The closest associates are Durand , Myrtle , and Flagg . Durand has a thinner loess cap. They form the dark colored member of a biosequence with Flagg and Myrtle soils. Ogle occurs on the same landscape as Flagg and Myrtle but generally farther away from streams.
Permeability is moderate.
Surface runoff is medium to rapid. The soils are used mostly for cultivated crops such as corn, small grains, and meadow. Native vegetation was prairie grass. Known extent is small but may be moderate depending on distribution in other states. Stephenson County, Illinois, 1969.
