Where to Find Bighorn Sheep in Unit S40
CPW's material on unit S40 stops at the boundary — there is no agency account of where its bighorn sheep live. 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 Larimer County.
The lines of the unit: CR 80C, CR 37 and South Branch Boxelder Creek
CPW has unit S40 bounded on the north by CRs 80C and 59 (Cherokee Park Rd.) and WY; on the east by CR 37, South Branch Boxelder Creek, Boxelder Creek, CR 19; on the south by CR 80 and U.S. 287; on the south and west by CRs 74E and 162 (Red Feather Lakes-Deadman Rd.). Read it as a frame, not as a hint about animals. 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: Deadman Hill, Little Bald Mountain and Black Mountain
Named high points inside the unit include Deadman Hill at 10,466 feet, Little Bald Mountain at 10,422 feet, Black Mountain at 9,941 feet, Boulder Ridge at 8,984 feet and Many Thunders Mountain at 8,474 feet. Several carry a public-land flag in our data, which makes them the first places to try for a view. Sheep need rock to escape into and will not stand far from it.
Holding ground: Wildcat Canyon, Columbine Canyon and Log Draw
Below them sit Wildcat Canyon at 7,637 feet, Columbine Canyon at 7,544 feet, Log Draw at 7,491 feet, Devils Canyon at 7,287 feet and Teakettle Canyon at 7,201 feet. Those are the basins, parks and bottoms this unit has, and they are what you glass into from above. Reaching the edge of one before light beats reaching its middle at noon.
Public ground to start from: Cherokee SWA, Cherokee SWA - Lone Pine Unit and Cherokee SWA - Lower Unit
CPW lists Cherokee SWA, Cherokee SWA - Lone Pine Unit, Cherokee SWA - Lower Unit, Cherokee SWA - Middle Unit and Cherokee SWA - Roy Brown Unit inside this unit as ground open to public hunting. Each property sets its own restrictions, and the agency's page for it is where they are written down. Federal land covers about 62% of the unit on top of those.
Water: Jimmy Creek Spring
Named sources include Jimmy Creek Spring. Nothing in the data says which of them run in autumn, so a scouting trip earns its fuel.
The herd this unit belongs to: RBS-01
CPW does not manage bighorn sheep unit by unit. It manages them as data analysis unit RBS-01, and unit S40 is one piece of it. The rest of RBS-01 is unit S1, unit S18 and unit S58. That matters twice over: the population objective and the licence numbers are set for the whole area, and the animals move across unit lines inside it without noticing them.

How to Hunt Bighorn Sheep in Unit S40
Bighorn Sheep Success Rates
CPW's 2023 harvest estimates carry no bighorn sheep row for unit S40 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. CPW's current harvest estimates are the place to check before you apply.

Open in Draw Odds EngineCPW's 2026 draw recap for bighorn sheep in unit S40, by hunt code, with resident and nonresident kept apart because the two draw from different licence pools:
- SMS40O2R — Rifle, 2nd Season, Ram Only, resident: 76 applicants for 1 licences, 1.3% drawn, 3 preference points needed
- SMS40O1R — Rifle, 1st Season, Ram Only, resident: 72 applicants for 1 licences, 1.4% drawn, 3 preference points needed
- SFS40O1R — Rifle, 1st Season, Ewe Only, resident: 23 applicants for 1 licences, 4.3% drawn, 3 preference points needed
Colorado runs a pure preference-point draw, so the point figure above is the requirement the agency published for that code in that year, not a forecast for the next one. Figures checked against CPW's own statistics pages on 2026-06-09.
