Little Rocky Mountains Backcountry Loop
Outlaw hideout country in Montana's forgotten range
Rising from the wheat fields like a forgotten island, the Little Rocky Mountains hide some of Montana’s most isolated 4WD terrain. This loop starts in Zortman, threading through the old Landusky mining district where Butch Cassidy once hid out. Mission Canyon cuts deep into volcanic rock, requiring careful navigation through loose shale and washouts. The ghost town of Landusky sits at mile 15, with stamp mill foundations still visible among the aspen groves.
Expert-level route due to steep canyon walls, unstable mining spoils, and creek crossings that can flash flood. Modified 4WD essential—stock vehicles won’t handle the embedded rocks in Mission Canyon or the off-camber sections above People’s Creek. May through October access, but spring runoff makes crossings dangerous until June. This is Fort Belknap reservation land, so respect tribal sovereignty and stick to established roads. No cell service, limited water sources. The reward is total isolation in Montana’s forgotten gold country.

Frequently asked questions
Do I need lockers for the Little Rocky Mountains Backcountry Loop?
Yes, lockers are highly recommended for the technical rock sections and canyon descents. Stock vehicles will struggle with the expert-level obstacles and steep grades.
Is this trail accessible during winter months?
No, the trail is only passable May through October due to snow closure and extreme weather conditions at elevation. Even late spring can have snow patches above 5000 feet.
Do I need permits to run this trail on Fort Belknap land?
Yes, you need permission from the Fort Belknap Indian Reservation before accessing this trail. Contact the tribal office in advance as access may be restricted or require escort.
What's the hardest section of the loop?
The canyon descents feature loose rock, off-camber shelves, and narrow ledges with significant exposure. Body damage is likely without careful line choice and spotters.
Are there reliable water sources for the 2-day trip?
Water crossings exist but sources may be seasonal or contaminated from old mining activity. Carry all water you'll need for the full 28-mile loop plus extra for emergencies.
