HD 388 covers the lower Smith River canyon and the country running east toward the Missouri Breaks above Fort Benton—deep, isolated canyon country where the Smith cuts through limestone and sandstone before joining the Missouri. Elevations run from about 2,800 feet on the river bottom to 4,500 feet on the surrounding bench-top prairie. The Smith River canyon itself is roadless for most of its 59-mile length, accessible only by float permit in the warm months. The bench-top country above the canyon is sage-and-grass prairie, dryland wheat where it can be plowed, with juniper and ponderosa-pine stringers in the rocky draws. Cottonwoods line the river bottom. Mule deer use the canyon rims and the timbered side coulees; whitetail concentrate in the cottonwood bottoms; elk move through the canyon country and bench-top rim country in real but small numbers; pronghorn on the prairie. Black bears use the canyon's berry crops in early fall. BLM, DNRC state, and private—the canyon corridor itself has a dense thicket of float-camp easements administered by FWP and the BLM, but the access reality is that you either float in (with a permit) or hike from public-trail entry points on the rim. Limited road access on the rim, and the BLM tracts are walk-in. Great Falls is the closest larger town—about an hour from the canyon's downstream end. White Sulphur Springs is upstream; Fort Benton is east on the Missouri. Cell service is gone basically anywhere off paved highway. The country is genuinely remote and the canyon access logistics are a real puzzle. For a hunter willing to figure out the float-and-camp logistics or hike the rim trails, this is one of the more unique hunts in the state.
