1965 Map of Thunderbolt Mountain

USGS Topo · Published 1991

About this map

Thunderbolt Mountain stands at the crest of a high ridgeline where Flathead Co and Lake County meet. This mid-1960s survey documents a wilderness landscape managed across three distinct jurisdictions: the Flathead National Forest, the Swan River State Forest, and the Bob Marshall Wilderness. Movement through this high-altitude terrain is defined by a network of historic routes including the Bunker Pack Trail and the Alpine Trail, which connect interior basins and peaks like Gildart Peak and Tranquil Mountain.
