Bighorn Sheep Hunting in Unit S203
Unit S203 lies in Missoula and Mineral counties. Montana FWP publishes no per-unit bighorn sheep success figure we can verify for this unit. Check land status on a current map before you plan a route.
Where to Find Bighorn Sheep in Unit S203
What Montana FWP publishes for unit S203 is a boundary, not a bighorn sheep map. Every place named below sits inside the unit line. Which of them holds animals in your season is for you to find out. The unit lies in Missoula and Mineral counties.
The lines of the unit: Fish Creek, Clark Fork River and Deep Creek
Montana FWP draws unit S203 in Missoula and Mineral counties with a boundary that runs on Highway 12, USFS Road 343, Interstate 90 and Route 30, and on Fish Creek, Clark Fork River and Deep Creek, walked corner by corner in its hunting district legal descriptions. That is a legal description, not a habitat map. Those features are what you will check against the map all week, and the divides among them are the ones that matter.
High ground inside the line: Petty Mountain, Telephone Butte and Deer Peak
Named high points inside the unit include Petty Mountain at 7,270 feet, Telephone Butte at 6,874 feet, Deer Peak at 6,705 feet, Blue Mountain at 6,453 feet and Martin Point at 6,018 feet. Several carry a public-land flag in our data, which makes them the first places to try for a view. Sheep on lower country still need rock, and on a desert unit the rock is the whole hunt.
Holding ground: Schoolhouse Gulch, Tucker Gulch and Anderson Gulch
Below them sit Schoolhouse Gulch at 3,548 feet, Tucker Gulch at 3,499 feet, Anderson Gulch at 3,466 feet, Hagerty Gulch at 3,463 feet and Indian Gulch at 3,454 feet. These are the folds worth watching, and the ones other hunters walk past on the way to somewhere steeper. Pick the one with the least road on its upwind side.
Water: Granite Springs and Martin Spring
Named sources include Granite Springs and Martin Spring. Nothing in the data says which of them run in autumn, so a scouting trip earns its fuel.

Bighorn Sheep Success Rates
Montana FWP's 2023 harvest estimates carry no bighorn sheep row for unit S203 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.
Bighorn Sheep Draw Odds
| Season | Tags | Applicants | Draw % | Pts (n/p) |

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 bighorn sheep record we can tie to unit S203. 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.
