Where to Find Bighorn Sheep in Unit S305
Montana FWP draws an exact line around unit S305 and says nothing about where the bighorn sheep stand inside it. 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 Park County.
The lines of the unit: Reese Creek, Yellowstone River and Beattie Gulch
Montana FWP draws unit S305 in Park County with a boundary that runs on Reese Creek, Yellowstone River, Beattie Gulch and Tom Miner CreekCinnabar Basin, walked corner by corner in its hunting district legal descriptions. It tells you the shape of the unit and nothing about its inhabitants. 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: Deaf Jim Knob, Cinnabar Mountain and Sphinx Mountain
Named high points inside the unit include Deaf Jim Knob at 8,203 feet, Cinnabar Mountain at 7,156 feet, Sphinx Mountain at 7,146 feet and Devils Slide at 6,484 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: Quaking Ash Hollow, Cinnabar Basin and Beattie Gulch
Below them sit Quaking Ash Hollow at 6,406 feet, Cinnabar Basin at 6,326 feet and Beattie Gulch at 5,240 feet. Those are the basins, parks and bottoms this unit has, and they are what you glass into from above. Work out which of them you can see from one position before you pick a camp.

Bighorn Sheep Success Rates
Montana FWP's 2023 harvest estimates carry no bighorn sheep row for unit S305 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 S305. 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.
