The Humbug Spires WSA is located in western Montana. Granite outcroppings, part of the Boulder Batholith, rise 300-600 feet and provide scenic interest and outstanding rock climbing opportunities. Hiking along the trail located in the wilderness winds along Moose Creek and through a mixed conifer forest, and then climbs a ridge and continues to the “Wedge," one of the more prominent and scenic spires.
From I-15, take Exit 99 (Moose Creek) and travel east about 3 miles on an improved gravel road to the trailhead parking area (restroom and kiosk present). The Wedge Trail leads approximately 3.2 miles from the parking area into the WSA.
