Elk Hunting in Unit 121
Unit 121 lies in Sanders County and covers about 978 square miles. Ground runs from 2,497 to 6,124 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 121
What Montana FWP publishes for unit 121 is a boundary, not a elk map. The country below is verified; where to begin in it is our judgement, not the agency's. The unit lies in Sanders County. It runs to about 978 square miles.
The lines of the unit: Emma Peak, Helwick Peak and Mosquito Peak
Montana FWP draws unit 121 in Sanders County with a boundary that runs on State Route 200, USFS Trail 433 and USFS Trail 528, and on Emma Peak, Helwick Peak, Mosquito Peak and Sievers Ridge, walked corner by corner in its hunting district legal descriptions. It tells you the shape of the unit and nothing about its inhabitants. Its value is practical — those are the features you will navigate by, and the ridges that separate one day's country from another's.
High ground inside the line: Snowshoe Peak, Vimy Ridge and A Peak
Named high points inside the unit include Snowshoe Peak at 8,706 feet, Vimy Ridge at 8,566 feet, A Peak at 8,537 feet, Saint Paul Peak at 7,666 feet and Ibex Peak at 7,625 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: Porcupine Pass, Silver Butte Pass and Snow Gulch
Below them sit Porcupine Pass at 5,074 feet, Silver Butte Pass at 4,251 feet, Snow Gulch at 4,002 feet, Happy Gulch at 4,000 feet and Hole-in-the-Wall at 3,852 feet. That is the low country of the unit — the ground animals drop into when they are pushed or when the weather turns. Reaching the edge of one before light beats reaching its middle at noon.
Water: Big Spring, Graves Creek Falls and Vermilion Falls
The water inside the unit line comes to 79 mapped stream reaches, 33 lakes and 154 stock tanks. Named sources include Big Spring, Graves Creek Falls and Vermilion Falls. On ground with that many tanks, knowing which two or three hold water in your season is the most useful thing a scouting trip can tell you.
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 2,497 feet to 6,124 feet, averaging 4,248 — enough relief to separate summer range from winter range.
Unit 121 terrain and land status
Measured from the unit boundary, not from the agency write-up
The lay of it
- 2,497–6,124 ft on a terrain sample , averaging 4,248 ft ; peaks can run higher.
- 977.9 sq mi inside the boundary. Big enough that picking one drainage beats driving three.
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
- 154 tanks
- 79 stream segments
- 33 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: Snowshoe Peak (8,706 ft), Saint Paul Peak (7,666 ft), Ibex Peak (7,625 ft), Flat Top Mountain (7,573 ft)
Holding ground: Milwaukee Pass (6,673 ft), Cube Iron Pass (6,574 ft), Vermilion Pass (6,013 ft), Big Spring, Graves Creek Falls
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 121 that we can read back to this unit on its own. Where the agency reports a unit inside a grouping, or prints a table our parser cannot resolve to a single column, we leave the number out rather than publish a statewide average as though it had been measured here. Montana FWP's current harvest estimates are the place to check before you apply.
Elk Draw Odds
| Season | Tags | Applicants | Draw % | Pts (n/p) |
|---|---|---|---|---|
| Rifle — B License either sex (resident) | 140 | 920 | 15.2% | — |
| Rifle — B License either sex (nonresident) | 9 | 51 | 17.6% | — |
Data from 2025 draw results. Each row is one residency pool — read the label before the number. This agency publishes no point thresholds, so the Pts column stays blank and these are pool odds, not what a point total draws.
Open in Draw Odds EngineMontana FWP's draw recap has no elk record we can tie to unit 121. 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. Rather than estimate a point requirement, we leave it blank — check Montana FWP's own draw recap for the hunt code you mean to apply for.
