Surficial Geology of North Dakota Image

Author: Bradley Miller

This image displays the distribution of surface geologic (parent) materials in North Dakota, interpreted to a depth of 2 meters using USDA-NRCS gSSURGO data. The map was developed by Iowa State University’s Geospatial Laboratory for Soil Informatics (GLSI), drawing from NRCS soil series descriptions and supplementary interpretation. Generalized geologic units include glacial till, loess, outwash, and other surficial deposits.
