1950 Map of Jefferson Island

USGS Topo · Published 1963

About this map

The Boulder River and Jefferson River converge in a landscape defined by ranching and resource extraction. Significant infrastructure from the Chicago Milwaukee ST Paul And Pacific and the Northern Pacific railroads follows the river valleys, connecting small settlements like Cardwell and Jefferson Island. The era is marked by a transition in land use, where local industry such as the Gypsum Mine (Inactive) and several Mines (Aban'd) sit alongside the emerging recreational draw of Lewis And Clark Cavern State Park.
