2018 Map of Thunder Mountain

About this map

Nicolet National Forest dominates this landscape on the border of Oconto and Marinette counties, where the terrain is defined by glacial kettle lakes and the complex drainage of the Thunder River. The topographic prominence of Thunder Mtn overlooks a dense network of water bodies, including Lackawanna Lake and the Caldron Falls Reservoir along the eastern edge. This area reflects a mid-20th-century transition toward recreational land use and forest management, evidenced by the numerous specialized tracks such as the Pipeline 4x4 Challenge Trail and various boat landings. Small, named water features like The Spring, Fryingpan Lake, and the curiously named Twin Bessies point to a long history of local naming conventions used by hunters and anglers who navigated these woods before modern development reached the area.
