Elk Hunting in Unit 391
Unit 391 lies in Broadwater and Lewis and Clark counties and covers about 470 square miles. Ground runs from 3,806 to 8,231 feet. Montana FWP publishes no per-unit elk success figure we can verify for this unit. Check land status on a current map before you plan a route.
Where to Find Elk in Unit 391
Montana FWP draws an exact line around unit 391 and says nothing about where the elk stand inside it. The country below is verified; where to begin in it is our judgement, not the agency's. The unit lies in Broadwater and Lewis and Clark counties. It runs to about 470 square miles.
The lines of the unit: Missouri River, Canyon Ferry Reservoir and Magpie Creek
Montana FWP draws unit 391 in Broadwater and Lewis and Clark counties with a boundary that runs on US Highway 12, Highway 287, USFS Road #359 and USFS Trail #234, and on Missouri River, Canyon Ferry Reservoir, Magpie Creek and Avalanche Creek, walked corner by corner in its hunting district legal descriptions. That is a legal description, not a habitat map. What it does give you is the way in: the rivers and highways you cross, and the divides that decide which drainage you end up in.
High ground inside the line: Mount Edith, Mount Baldy and Boulder Mountain
Named high points inside the unit include Mount Edith at 9,493 feet, Mount Baldy at 9,441 feet, Boulder Mountain at 8,812 feet, Windy Ridge at 7,851 feet and Grassy Mountain at 7,688 feet. Several carry a public-land flag in our data, which makes them the first places to try for a view. Elk on low, open country live on distance and visibility, so they see you first.
Holding ground: Lucky Gulch, Left Hand Fork White Gulch and Irish Gulch
Below them sit Lucky Gulch at 5,317 feet, Left Hand Fork White Gulch at 5,306 feet, Irish Gulch at 5,304 feet, Cement Gulch at 5,214 feet and Corral Gulch at 5,080 feet. Those are the basins, parks and bottoms this unit has, and they are what you glass into from above. Pick the one with the least road on its upwind side.
Water: Roberts Spring
The water inside the unit line comes to 49 mapped stream reaches, 5 lakes and 17 stock tanks. Named sources include Roberts Spring. Nothing in the data says which of them run in autumn, so a scouting trip earns its fuel.
Reading the land status
Our ownership read for this unit is approximate — it comes out as National Forest 60%, Private / Other 32% and State Trust 8%, so treat it as a starting point and check a current land-status layer before you plan a route. The unit runs from 3,806 feet to 8,231 feet, averaging 5,361 — that is a lot of vertical to cover, and it means the season you draw decides which half of the unit you hunt.
Unit 391 terrain and land status
Measured from the unit boundary, not from the agency write-up
The lay of it
- 3,806–8,231 ft on a terrain sample , averaging 5,361 ft ; peaks can run higher. That spread means you can hunt two seasons in one day — plan clothing for both ends.
- 470.3 sq mi inside the boundary.
Who owns the ground
- National Forest — 60%
- State Trust — 8%
- Private / Other — 32%
Roughly 68% is public. Carry a land-status layer anyway — these are area percentages, not a map of where the boundaries fall.
Water on the ground
- 17 tanks
- 49 stream segments
- 5 lakes
Counts from mapping data, so this is how many exist, not how many hold water in a dry year. Sitting water only pays where you find fresh tracks.
Named features inside the unit
Glass from: Mount Edith (9,493 ft), Mount Baldy (9,441 ft), Boulder Mountain (8,812 ft), Grassy Mountain (7,688 ft)
Holding ground: Ready Cash Gulch (5,850 ft), Holloway Gulch (5,579 ft), Debauch Gulch (5,412 ft), Roberts Spring
Every one of these was tested against the unit polygon before it went on the map. They are starting points, not agency recommendations.

Elk Success Rates
Montana FWP's 2023 harvest estimates carry no elk row for unit 391 that we can read back to this unit on its own.

Montana FWP's current harvest estimates are the place to check before you apply.

That usually means the licence is sold over the counter, is issued under a hunt code covering several units, or was not offered in the years we hold.
