Unit A77 (Fifteen Mile Creek)

The Wyoming Game and Fish Commission names antelope hunt area 77 "Fifteen Mile Creek". It runs to about 1,127 square miles, in Big Horn (45%), Washakie (31%), Park (19%) and Hot Springs (5%) counties. WGFD reports these pronghorn as the Fifteen Mile herd unit, which also takes in antelope hunt areas 83 and 110. What WGFD publishes for the area is its boundary and its harvest; where the pronghorn stand inside it is our reading of the ground, and the two are kept apart below.

The line: Greybull River and Bighorn River

WGFD's 2026 Chapter 5 walks the line around antelope hunt area 77 corner by corner. It starts at the town of Meeteetse. On the way round it follows Wyoming Highway 432, Wyoming Highway 431, U.S. Highway 20 and U.S. Highway 120, and Greybull River and Bighorn River. Read it as the legal edge of your license rather than as a hint about animals. The full text is in Section 5 of that chapter, with this year's season dates and license limitations in Section 2.

Not the same ground as the other hunt area 77s

WGFD numbers each species' hunt areas on its own grid, so the number 77 also belongs to its elk and deer hunt areas 77. 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 antelope area, and the cards at the foot of the page link the others.

Ground WGFD opens: Greybull River and Washakie 1

Its Access Yes program enrolls a Hunter Management Area here that list antelope among their species — Greybull River (18,851 acres). WGFD also lists 11 Walk-In Areas covering about 11,634 acres open for antelope, among them Washakie 1, Washakie 21 and Washakie 25. WGFD's 2026 regulations open Access Yes land only for the species and dates listed for each area, with each area's own rules on WGFD's site and no motorized travel unless WGFD says otherwise.

High ground inside the line: Sheets Mountain, Tatman Mountain and West Crow Woman Butte

Named high points inside antelope hunt area 77 include Sheets Mountain at 6,275 feet, Tatman Mountain at 6,251 feet, West Crow Woman Butte at 6,163 feet, Buck Buttes at 6,161 feet and Crow Woman Buttes at 6,152 feet. Several carry a public-land flag in our data, which makes them the first places to try for a view. Pronghorn live in the open and trust their eyes, which is the whole problem.

Holding ground: Gillies Draw, Horseshoe Bedground and Badger Creek Basin

Below them sit Gillies Draw at 5,205 feet, Horseshoe Bedground at 5,190 feet, Badger Creek Basin at 5,098 feet, Blackstone Gulch at 5,063 feet and McGee Gulch at 5,033 feet. These are the folds worth watching, and the ones other hunters walk past.

Water: Baking Powder Springs, Parker Springs and Sand Spring

Named water inside the line includes Baking Powder Springs, Parker Springs, Sand Spring and Wilson 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 antelope hunt area 77 runs from 3,935 feet to 6,275 feet. Those are the heights of the features GNIS names, which bound the range from inside rather than measure it.

Wyoming Game and Fish's 2025 harvest survey estimates 170 hunters took 155 pronghorn in antelope hunt area 77 — 91.2% success, at about 3.9 days of hunting for every animal taken. Residents ran 86.7% and nonresidents 102% that year. Most hunters who held a license here filled it, so the real question is the draw, not the hunting. The plan: spot from a vehicle or a rise at distance, then plan a stalk that uses the only cover there is — the curve of the ground.

License types WGFD reported in antelope hunt area 77 for 2025

WGFD's 2025 survey breaks the pronghorn harvest in antelope hunt area 77 down by license type.

• Type 1 — 113 licenses in use, 88.5% success, 3.9 days per animal
• Type 6 — 25 licenses in use, 72% success, 5 days per animal
• Type 7 — 26 licenses in use, 96.2% success, 3.6 days per animal
• Type 8 — 21 licenses in use, 57.1% success, 3.4 days per animal

What each type allows — antlered, antlerless, archery-only, where it is valid — and this year's dates are set area by area in Section 2 of WGFD's 2026 Chapter 5, so read the line for the license you hold rather than assume it matches another area's.

Glassing from Sawtooth, East Ridge and Bull Knoll

Take a position on one of Sawtooth (5,769 ft), East Ridge (5,717 ft), Bull Knoll (5,611 ft) and Whistle Berry Hill (5,511 ft) and be on it before light. Cold air slides downhill in the dark, so keep your scent out of the bowl you mean to watch, and expect the thermals to turn uphill an hour after the sun reaches the slope. Early-season bucks hold does and can be decoyed where the law allows it.

Hunting the Access Yes ground

Hunter Management Areas and Walk-In Areas are private land opened through WGFD's Access Yes program, and the 2026 regulations open each one only for the species and dates listed for it. Read the area's page on WGFD's site before you go — its rules, its dates and whether it needs anything more than your license. Anything else on that land, or any species not listed, needs the landowner's permission, so treat the Access Yes line as the edge of what you were given.

Reading the Fifteen Mile herd, not just the area

WGFD's harvest report also tabulates pronghorn by herd unit, and antelope hunt area 77 shares the Fifteen Mile herd unit with antelope hunt areas 83 and 110. The animals cross those lines without noticing them, so a neighbouring area in the same herd is the fairest comparison for a season here.

The way in: Wyoming Highway 432, Wyoming Highway 431 and U.S. Highway 20

We hold no road inventory for antelope hunt area 77, so the only routes we can name are the ones WGFD draws its boundary with: Wyoming Highway 432, Wyoming Highway 431, U.S. Highway 20 and U.S. Highway 120. Those are its edges, not its interior — where you leave the pavement, not what the inside is like. Check each on a current motor-vehicle-use map before you count on it, because a road in a legal description isn't a promise of public access.
