2020 Map of Thunderbolt Creek

About this map

The Continental Divide National Scenic Trail winds through high-altitude terrain where Jefferson and Powell counties meet. This mountain landscape is defined by the massive crest of the Continental Divide, separating the drainages of the Helena National Forest to the north and the Deerlodge National Forest to the south. Notable peaks like Electric Peak and Thunderbolt Mtn tower over a network of seasonal streams and gulches, including Boyle Gulch and Finn Gulch. In the lower elevations, the Boulder River valley provides a corridor for travel along Boulder River Rd. This survey documents a wilderness environment where landmarks such as Berkin Flat and Cottonwood Lake serve as key navigational points for those navigating the backcountry. The map also traces various forest management routes like the Red Rock Connection, reflecting the area's ongoing use for conservation and recreation.
