1950 Map of Jefferson Island

USGS Topo · Published 1970

About this map

Lewis And Clark Cavern State Park dominates the central landscape of this 1950s era survey, where the Jefferson River winds through narrow passages. The confluence of the river with the Boulder River and South Boulder River creates a complex network of waterways, including the Jefferson Slough, which defined the local agricultural and ranching patterns of the time. The transition from the rugged London Hills to the valley floor is marked by numerous family holdings, such as the Brenner Ranch, Pryor Ranch, and Watson Ranch.
