About this map

Peshtigo River rapids and secluded logging-era settlements define this 1940 layout of the Wisconsin Northwoods. The map captures a landscape in transition, where the Caldron Falls Reservoir has been established but significant portions remain noted as an Unsurveyed Area. The presence of the Mc Caslin Fire Tower and Thunder Mountain Fire Tower reflects the vital forest fire management infrastructure of the era.

Remote outposts and rural institutions like the Silver Cliff Sch and Shady Nook Sch appear alongside industry markers such as a local Lumber Yard and the State Fish Hatchery. For genealogists, the map preserves specific points of interest like the Babson settlement and small named lakes including Newman L and Crane Lake, documenting the early footprint of the Silver Cliff region before modern development.
