2014 Map of Thunderbolt Creek

About this map

The Continental Divide winds through the high country of Jefferson and Powell Counties, marking a significant hydrologic boundary within the Helena National Forest and Deerlodge National Forest. This section of the Rockies is defined by prominent summits such as Electric Peak and Thunderbolt Mtn, which overlook a network of drainages feeding the Boulder River. The landscape is etched with numerous named gulches and flats, including Finn Gulch, Alta Gulch, and Berkin Flat, suggesting a history of land use and navigation in these steep drainages. High-altitude water bodies like Cottonwood Lake and Cliff Lake occupy basins between the peaks. A system of forest roads, notably the Red Rock Connection and Thunderbolt Creek Rd, provides access across the rugged terrain, following the natural contours of the mountains and the path of Thunderbolt Creek toward the valley floor.
