Algona Moraine: Iowa Landforms Revealed
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.
The elevated curved features in this map are glacial moraines deposited during the most recent period of glaciation in north-central Iowa. The largest in this view is called the Algona Moraine.
