Unit S622 lies in Valley and Phillips 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 S622
Montana FWP's material on unit S622 stops at the boundary — there is no agency account of where its bighorn sheep live. So the ground below is the unit's own and the read on where to start is ours, labelled as such. The unit lies in Valley and Phillips counties.
The lines of the unit: Fort Peck Reservoir, Willow Creek and Larb Creek
Montana FWP draws unit S622 in Valley and Phillips counties with a boundary that runs on Fort Peck Reservoir, Willow Creek, Larb Creek and First Creek, walked corner by corner in its hunting district legal descriptions. Read it as a frame, not as a hint about animals. 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: Coal Mine Hill, Larb Hills and Swede Ridge
Named high points inside the unit include Coal Mine Hill at 3,350 feet, Larb Hills at 3,222 feet, Swede Ridge at 3,165 feet, Iron Stake Ridge at 3,126 feet and Blue Ridge at 3,125 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: Berry Coulee, Johnston Coulee and North Shotgun Coulee
Below them sit Berry Coulee at 2,614 feet, Johnston Coulee at 2,602 feet, North Shotgun Coulee at 2,586 feet, Coal Mine Coulee at 2,586 feet and South Shotgun Coulee at 2,583 feet. That is the low country of the unit — the ground animals drop into when they are pushed or when the weather turns. 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 S622 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) |

| Rifle — General either sex (nonresident) | 1 | 1,279 | 0.1% | — |
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 S622. 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.
