1981 Map of Long Lake

USGS Topo · Published 1982

About this map

Horseshoe Valley and the surrounding prairie of McLean County are defined by a complex network of glacial potholes and seasonal wetlands, as seen in this early 1980s topographic study. The landscape is dominated by Long Lake and Crooked Lake, with significant portions of the terrain dedicated to conservation through the Camp Lake National Wildlife Refuge and the National Waterfowl Production Area. These protected spaces highlight the region's importance for migratory birds within the Great Plains flyway.
