Bighorn Sheep Hunting in Unit S304

Unit S304 lies in Gallatin and Park 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 S304

Montana FWP draws an exact line around unit S304 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 Gallatin and Park counties.

The lines of the unit: Big Creek, Bark Cabin Creek and Moose Creek

Montana FWP draws unit S304 in Gallatin and Park counties with a boundary that runs on Highway 191, Route 84, Interstate 90 and Highway 89, and on Big Creek, Bark Cabin Creek and Moose Creek, walked corner by corner in its hunting district legal descriptions. That is a legal description, not a habitat map. 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: Mount Bole, Hyalite Ridge and Mount Chisholm

Named high points inside the unit include Mount Bole at 10,312 feet, Hyalite Ridge at 10,312 feet, Mount Chisholm at 10,312 feet, Hyalite Peak at 10,291 feet and Overlook Mountain at 10,230 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: Dean Gulch, Shoefelt Gulch and Morrison Gulch

Below them sit Dean Gulch at 5,835 feet, Shoefelt Gulch at 5,738 feet, Morrison Gulch at 5,716 feet, Dry Gulch at 5,678 feet and Big Draw at 5,674 feet. Those are the basins, parks and bottoms this unit has, and they are what you glass into from above. Two you can watch from a single knob is worth more than five you have to drive between.

Water: Langohr Springs

Named sources include Langohr Springs. Nothing in the data says which of them run in autumn, so a scouting trip earns its fuel.

Unit S304 terrain and land status

Measured from the unit boundary, not from the agency write-up

Named features inside the unit

Glass from: Mount Bole (10,312 ft), Mount Chisholm (10,312 ft), Hyalite Peak (10,291 ft), Mount Blackmore (10,134 ft)

Holding ground: Horseshoe Basin (9,211 ft), Tom Lay Prairie (6,933 ft), Wheeler Gulch (6,011 ft), Langohr Springs

Every one of these was tested against the unit polygon before it went on the map. They are starting points, not agency recommendations.

How to Hunt Bighorn Sheep in Unit S304

Montana FWP publishes no bighorn sheep success figure for unit S304 that we can tie to this unit alone, so we won't quote one. The plan: pick a glassing position across from the escape terrain and stay on it for hours, not minutes.

Glassing from Divide Peak, Alex Lowe Peak and Flanders Mountain

Take a position on one of Divide Peak (10,030 ft), Alex Lowe Peak (10,010 ft), Flanders Mountain (9,946 ft) and Palace Butte (9,890 ft) and be on it before light. Work the morning with the air falling away from you, then accept that by mid-morning the wind has reversed and the plan has to change with it. A tripod is worth more here than another hour of walking. On the rut hunts, late hunts put rams with ewe groups on the same rock.

The way in: Highway 191, Route 84 and Interstate 90

We have no road inventory for this unit, so the only routes we can name are the ones Montana FWP draws the boundary with: Highway 191, Route 84, Interstate 90 and Highway 89. Those are its edges, not its interior — useful because they are where you leave the pavement, and useless for telling you what the inside is like. Check each of them on a current motor-vehicle-use map before you count on it, because a line on a boundary description is not a promise of public access.

A first plan from the pins on this page

The map above marks Mount Bole, Mount Chisholm, Hyalite Peak and Mount Blackmore as places to see from, and Horseshoe Basin, Tom Lay Prairie, Wheeler Gulch and Langohr Springs as ground to watch. Each pin is a named feature verified to fall inside the unit line, not a spot anyone has hunted. Join two of them into a morning: be on the first before light, move to the second once the thermals turn.

What we can't tell you

Some of the ground named above carries no land-status flag we trust, so check ownership on a current layer before you hunt it. We have no bighorn sheep success figure for this unit that survives checking against Montana FWP's own harvest and hunter counts, and we would rather say so than print a statewide average as though it were measured here.

Montana rules that decide your day

Summarised from FWP regulations. They change — read the current regulations and your permit-tag before you hunt.

Legal shooting hours

Big game may be taken from half an hour before sunrise to half an hour after sunset.

Motorized retrieval

Montana has no general off-road retrieval allowance; travel stays on open routes.

Tagging

Validate the tag and attach it to the carcass before moving the animal.

Leaving meat

Wasting game meat is illegal.

Where you may not shoot

Occupied structures — No discharging a firearm within 150 yards of an occupied dwelling without permission, and no shooting from or across a public road.

Bighorn Sheep: where to put the shot

Broadside or quartering away, on the back edge of the front leg about a third of the way up the body.

Shots to refuse

Nothing behind or overlapping the animal you picked.
Your maximum range is the farthest you have shot a three-shot group into a paper plate from the rest you are carrying.
Pass the shot you are talking yourself into.

Plan the carry: roughly 40– 120 lb of boned-out meat, before head and hide — two large coolers. ProHunt planning estimate, not an agency figure.

Bighorn Sheep Success Rates

Montana FWP's 2023 harvest estimates carry no bighorn sheep row for unit S304 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 (resident)	1	249	0.4%	—

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 Engine

Montana FWP's draw recap has no bighorn sheep record we can tie to unit S304. 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.

Unit Logistics & Expectations

Planning Notes

🥾

Terrain Difficulty

Very strenuous. Cliff, scree, and multi-day backcountry travel are the norm.

👥

Hunting Pressure

Low for sheep specifically because the quota is so small, but general recreation is present in road-accessible portions.

🌦️

Weather

Expect high wind, cold fronts, and possible snow at elevation. Plan for shelter and extended bivy capability.

📋

Permit Notes

All HD 304-20 permits are issued through FWP's special drawing.

Note: Coordinate pack-animal or solo-pack-out recovery in advance; some cliff-country kills require a multi-trip retrieval.
