Today we are celebrating Geologic Map Day, to promote awareness of geologic mapping and its importance to society. Here is a map of the Bedrock Geologic Map of Iowa created by a team at the Iowa Geological and Water Survey. For details about each of the geologic regions click here to read the report. Which
Obscured from view by vegetation and built structures, Iowa’s often subtle landforms are revealed through a LiDAR-derived bare earth digital elevation model in a Geographic Information System. Geological and human made features can be seen in this series of LiDAR color hillshade maps from across the State. Loess Deep deposits of wind-blown silt define the

This spring, Gregg Hadish of USDA Natural Resource Conservation Service and staff member of ISU GIS Facility put together a series of images called Iowa Landforms Revealed. The project looks at Iowa geological features using LiDAR. Gregg also used interesting color ramps to give these images an artistic component, inspired by the USGS Earth as
