1951 Map of Thunder Mountain

About this map

The Peshtigo River carves through this northern landscape, defining a region of hydraulic power and recreation. As seen in the early 1950s, the river is marked by series of natural obstacles and landmarks including Wilson Rapids, Roaring Rapids, and Jerry Chute. This portion of the Nicolet National Forest is characterized by its dense network of glacial lakes and wetlands, where isolated features like the Shady Nook Sch and McClintock Park served a small, localized population. A primary focus of the 1951 field examination was fire observation, evidenced by the strategic positioning of the McCaslin Lookout Tower and the Thunder Mountain Lookout Tower atop the local high points. These towers, along with a complex of designated Fire Lanes, provide a detailed view of the mid-century forestry infrastructure within Marinette and Oconto counties.
