HD 401 covers the Sun River drainage and the Rocky Mountain Front country east of Augusta—classic Front Range prairie-meets-mountains terrain. Elevations range from about 4,000 feet on the prairie benchlands to 8,500 feet on the timbered Front Range ridges. The eastern portion is rolling grassland and hay fields dissected by shallow coulees and creek bottoms. Heading west, the terrain ramps up through fescue-covered foothills into the Douglas fir and lodgepole forests of the Front Range. The Sun River and its forks drain east out of the Bob Marshall Wilderness, and the surrounding country serves as transition range for elk, mule deer, and grizzly bears moving between the wilderness and the prairie. This is the leading edge of grizzly range on the Front—bear awareness is not optional.
Lewis and Clark National Forest, BLM, state trust, and private ranch land share the landscape. US-287 and the Augusta-to-Benchmark road provide the main access. Block management ranches are common in this HD and provide critical access to private land. Augusta is the gateway town—small but functional with gas, supplies, and a deep outfitting tradition. Great Falls is about 70 miles east. Choteau serves the northern portions. Cell service works near Augusta and fades heading west. This HD connects to the larger Sun River elk herd story—animals that summer in the Bob Marshall migrate through this country, and the timing of that migration drives the hunting. Early-season hunts focus on resident animals in the foothills; late-season hunts coincide with the migration push. Wind on the Front is legendary and constant—it shapes the vegetation, the terrain, and your hunting approach. Glass from the prairie vantage points into the timbered foothills at first and last light.
HD 401 (Sun River prairie / Rocky Mountain Front east of Augusta) connects to the larger Sun River elk herd story — animals that summer in the Bob Marshall Wilderness migrate through this country en route to winter range. General elk tags are available OTC for residents. Lewis and Clark National Forest, BLM, state trust, and private ranch land share the landscape. Block Management ranches are common and provide critical access to private land. Wind on the Rocky Mountain Front is legendary and constant — it shapes vegetation, terrain, and hunting approach. Grizzly bear presence is increasing as bears expand from the wilderness onto the prairie — bear awareness is mandatory. Bull-to-cow ratios are moderate. Early-season hunts focus on resident animals in the foothills; late-season hunts coincide with the migration push off the Continental Divide. The open prairie allows long-range glassing into the timbered foothills at first and last light. Augusta has a deep outfitting tradition and is the gateway town. This HD provides the front-range portion of the Sun River elk experience without requiring a wilderness pack-in trip.

Recent Trophy Scores · 2020–2025
Trophy score data is tracked by county, so the overlap with GMU boundaries is approximate. These numbers tell you whether the area is capable of growing big animals — they do not indicate public vs. private land. Big elk can come from anywhere; most elk in the lower 48 trace back to Yellowstone stock that was transplanted west after the species was nearly extirpated in the early 1900s.

Montana Unit 401 draw odds — every hunt, by species
Odds = tags ÷ applicants for the latest year on file, per applicant pool — resident, nonresident, outfitter and every other pool the state runs. Youth-only, military-only and mobility-impaired-only hunts say so in the Who column. Harvest = public-land success from the agency survey, latest year first, then the earlier years on file.
