This historic cabin, built in 1905, is located approximately 14 miles south of Dillon, Montana, on the banks of the Beaverhead River. The cabin provides access to a variety of outdoor recreational activities on adjacent public lands. The cabin and surrounding lands are managed by the Bureau of Land Management.
Recreation
Recreation opportunities are right outside the door with world-class trout fishing on the Beaverhead River. There may also be opportunities for waterfowl hunting. Nearby opportunities for hunting, hiking, fishing, and 4WD touring through the mountains are plentiful.
Facilities
The cabin sleeps a maximum of eight people on two queen size fold-out futons, and four bunk beds; bedding is not provided. A propane stove/oven, lights, and small refrigerator, wood cook stove, wood stove, outhouse, non-potable water pump, and basic cooking and eating utensils are provided. No potable water is available.

Getting there
Access to the cabin is a short distance off I-15 south of Dillon. From Dillon, take the Dalys exit (#51) and turn left under the interstate, then right on the frontage road approximately 1/4 mile to an access gate and parking area on your left. You will need a combination to open the locked gate, and should lock the gate behind you to prevent other unauthorized vehicle use on this road. From here, the cabin is only 1/4 mile ahead on a lightly maintained gravel road.
