Where to Find Bighorn Sheep in Unit S330

Montana FWP's material on unit S330 stops at the boundary — there is no agency account of where its bighorn sheep live. The country below is verified; where to begin in it is our judgement, not the agency's. The unit lies in Madison and Beaverhead counties.

What bounds unit S330

Montana FWP draws unit S330 in Madison and Beaverhead counties with a boundary that runs on Highway 41, USFS Road 347, USFS Road 290 and USFS Road 324, and on Long Creek, walked corner by corner in its hunting district legal descriptions. That is a legal description, not a habitat map. 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: Sunset Peak, Hogback Mountain and Black Butte

Named high points inside the unit include Sunset Peak at 10,565 feet, Hogback Mountain at 10,561 feet, Black Butte at 10,521 feet, Olson Peak at 10,455 feet and Sliderock Mountain at 10,429 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: Eureka Basin, Maverick Basin and Pole Creek Basin

Below them sit Eureka Basin at 8,007 feet, Maverick Basin at 7,836 feet, Pole Creek Basin at 7,521 feet, Bachelor Gulch at 7,055 feet and Mill Gulch at 7,028 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.

Water: Kelly Spring, Timber Creek Spring and Pole Patch Spring

Named sources include Kelly Spring, Timber Creek Spring, Pole Patch Spring, Mud Spring, Warm Springs and Caldwell Springs. Nothing in the data says which of them run in autumn, so a scouting trip earns its fuel.

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 S330

Montana FWP publishes no bighorn sheep success figure for unit S330 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 Sawtooth Mountain, Snowcrest Range and Sheep Mountain

Take a position on one of Sawtooth Mountain (10,057 ft), Snowcrest Range (10,056 ft), Sheep Mountain (9,684 ft) and Greenhorn Range (9,684 ft) and be on it before light. In the dark the air runs downhill. Pick an approach that doesn't send it into the country you want to see, and plan to move once the slope warms. Give a basin forty minutes before you decide it is empty. On the rut hunts, late hunts put rams with ewe groups on the same rock.

The way in: Highway 41, USFS Road 347 and USFS Road 290

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 41, USFS Road 347, USFS Road 290, USFS Road 324 and US Highway 287. 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. Pick the edge nearest the country you mean to hunt and work in from it on foot, rather than driving the perimeter looking for a way through.

A first plan from the pins on this page

The map above marks Sunset Peak, Hogback Mountain, Black Butte and Sliderock Mountain as places to see from, and Honeymoon Park, Peterson Basin, Antone Pass and Kelly Spring 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 S330 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	281	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.

Montana FWP's draw recap has no bighorn sheep record we can tie to unit S330. 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

🛣️

Road Conditions

Access combines paved highway, county gravel, and rough forest roads. Early snow and mud can close upper roads. We recommend a capable 4WD truck and current motor vehicle use maps.

👥

Hunting Pressure

Pressure is minimal during the season itself — one tag means minimal competition — but scouting pressure can be heavy from other applicants and outfitters working the district.

🌦️

Weather

Sheep seasons span warm September conditions through cold, potentially snowy November weather. Pack layered systems and expect rapidly changing mountain conditions.

📋

Permit Notes

All licenses for this district are issued through FWP's sheep special drawing. We recommend confirming the current permit code and applying by the posted deadline.

Note: Hire or consult a local guide service at least for the scouting phase if time is tight — boots-on-the-ground intel is invaluable for a once-in-a-lifetime tag.
