COMPETING SERIES: These are the Aubbeenaubbee, Crosier, Haskins, Lamberjack, and Shebeon series. Aubbeenaubbee soils contain more than 52 percent sand in the upper part of the series control section. Crosier soils do not have strata or subhorizons of loamy sand or coarser (averaging more than 80 percent sand) in the lower part of the control section. Haskins soils average less than 80 percent sand in the lower part of the series control section. Lamberjack soils have more than 15 percent rock fragments in the lower part of the argillic horizon. Shebeon soils have sola less than 40 inches thick.
GEOGRAPHIC SETTING: Baugo soils formed in loamy and sandy outwash overlying loamy dense till and are on swells on till plains. Slope gradients range from 0 to 1 percent. Mean annual temperature ranges from 50 to 52 degrees F., mean annual precipitation ranges from 32 to 40 inches, frost-free period ranges from 150 to 180 days, and elevation ranges from 600 to 1,530 feet above sea level.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Brookston, Crosier, and Rensselaer soils. The poorly drained Brookston soils and the very poorly drained or poorly drained Rensselaer soils are in depressions. The somewhat poorly drained Crosier soils are on slightly higher swells.
DRAINAGE AND PERMEABILITY: Somewhat poorly drained. The potential for surface runoff is negligible to low. Permeability is moderate in the solum, rapid in the upper part of the underlying material, and slow in the dense till. The depth to the top of a perched seasonal high water table ranges from 0.5 to 1.5 feet for some time in normal years.
USE AND VEGETATION: Soils are used to grow corn, soybeans, wheat, and hay. Native vegetation is deciduous forest.
DISTRIBUTION AND EXTENT: MLRA 111 in northern Indiana. The soils are of small extent.
MLRA OFFICE RESPONSIBLE: Indianapolis, Indiana.
SERIES ESTABLISHED: Elkhart County, Indiana, 1997.

NASIS Data Mapunit ID 124243 represents the typical pedon.
ADDITIONAL DATA: Lab characterization data is available for the typical pedon (S95IN-039-008) from the National Soil Survey Laboratory, Lincoln, NE. Transect data (T95IN-039-068) is on file in the MLRA project office in Plymouth, Indiana. Transect shows 70 percent Baugo, 20 percent Del Rey-till substratum, and 10 percent Rensselaer-till substratum soils.
