Surficial Geology of Wisconsin Image
| Updated:
Author: Bradley Miller
This image illustrates the surface geologic (parent) materials of Wisconsin, interpreted to a 2-meter depth using USDA-NRCS gSSURGO data. Classifications were created by Iowa State University’s Geospatial Laboratory for Soil Informatics (GLSI), using NRCS soil series descriptions and additional interpretation based on spatial and morphological data. It includes generalized materials such as glacial till, loess, outwash, residuum, and alluvium.
