Where to Find Bighorn Sheep in Bighorn Sheep Hunt Area 20
The Wyoming Game and Fish Commission names bighorn sheep hunt area 20 "Kouba Canyon". It runs to about 245 square miles, entirely in Weston County. What WGFD publishes for the area is its boundary and its harvest; where the bighorn sheep stand inside it is our reading of the ground, and the two are kept apart below.
Where bighorn sheep hunt area 20 begins and ends
WGFD's 2026 Chapter 9 defines bighorn sheep hunt area 20 as beginning where U.S. Highway 85 crosses the Wyoming � South Dakota state line; southerly along said line to the Dewey Road (Weston County Rd. #2); northwesterly along said road to U.S. Highway 85; northerly along said highway to the Wyoming-South Dakota state line. That is a legal description, not a habitat map, and it is the text a warden reads you against. The full text is in Section 6 of that chapter, with this year's season dates and license limitations in Section 3.
Not the same ground as the other hunt area 20s
WGFD numbers each species' hunt areas on its own grid, so the number 20 also belongs to its antelope and moose hunt areas 20. None of them shares a county with this one. A license is good only in the hunt area of its own species, so this page is about the bighorn sheep area, and the cards at the foot of the page link the others.
High ground inside the line: Mount Pisgah, Red Butte and Frannie Peak
Named high points inside bighorn sheep hunt area 20 include Mount Pisgah at 6,401 feet, Red Butte at 5,718 feet, Frannie Peak at 5,284 feet and Wyoming Hill at 3,835 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: Thoeming Draw, Deadman Draw and Thomson Canyon
Below them sit Thoeming Draw at 5,124 feet, Deadman Draw at 4,928 feet, Thomson Canyon at 4,920 feet, Brown Canyon at 4,877 feet and North Thomson Canyon at 4,855 feet. Those are the basins and bottoms of the area, and they are what you glass into from above.
Water: Ferguson Spring, Mix Spring and Slate Spring
Named water inside the line includes Ferguson Spring, Mix Spring, Slate Spring, Austin Spring and State Line Spring. Nothing in the data says which of it runs in autumn, so a scouting trip earns its fuel.
Reading the land status
Named ground inside bighorn sheep hunt area 20 runs from 3,835 feet to 6,401 feet. Those are the heights of the features GNIS names, which bound the range from inside rather than measure it.

Search Wyoming Draw OddsWyoming Game and Fish's 2026 demand report for bighorn sheep in bighorn sheep hunt area 20, residents and nonresidents kept apart because they draw from different license pools:
- Type 1 (any ram), residents: 101 first-choice applicants for 0 licenses, 0% drawn
WGFD draws full-price bighorn sheep licenses partly on preference points, for residents and nonresidents alike, highest balance first (Chapter 44, Section 19); the figures above are from its random draw. Drawing a full-price license deletes your bighorn sheep points, and after a full-price bighorn sheep license from the initial drawing you may not apply for one again. WGFD publishes no preference-point level at which a hunt draws, so none is given here. Every figure was checked against WGFD's demand-report PDFs on 2026-08-10.
