1971 Map of Thornapple

USGS Topo · Published 1973

About this map

The Flambeau River carves a winding path through this corner of Rusk County, punctuated by the engineering of the Thornapple Dam and the riverside settlement of Port Arthur. This early 1970s landscape is a mix of active utility and receding industrial history, where the modern Soo Line tracks run parallel to a visible Old Railroad Grade that speaks to earlier logging or transit routes. The presence of the Ladysmith Lookout Tower and Air Village Landing Field indicates the area's role in regional fire monitoring and early aviation.
