Montana Elk Mule Deer Moose

Unit 100 (Bitterroot Valley)

Montana Hunting Guide — Elk, Mule Deer, Moose

HD 100 covers the main Bitterroot Valley floor and lower Bitterroot River drainages in Ravalli County, southwest Montana. The unit blends private ranch land along the valley bottom with Bitterroot National Forest foothills rising to the east. Elk move seasonally between summer range on the Sapphire Mountains to the east and winter forage on lower valley bench land. General season cow-elk licenses are over-the-counter for residents while antlered bull opportunities require careful review of current FWP regulation lists. Hunting pressure is moderate given the mix of public and private land and good road access.

Elk Hunting in Unit 100

Where to Find Elk in HD 100

Elk in HD 100 follow classic Bitterroot Valley migration patterns, moving between high-elevation summer range on the Sapphire Mountains to the east and lower-elevation wintering grounds on valley benches and foothills. Early season elk concentrate near 5,000–7,000 feet in the timber just inside Bitterroot National Forest along the east-side drainages including Sweeney Creek, Blodgett Canyon, and Bass Creek.

Early Season (September–October)

During archery season, bulls use the steep timbered draws feeding into the valley from the Sapphire front. Wallows exist along the seep lines in mixed Douglas fir and lodgepole timber. Thermals in these east-facing canyons rise predictably in early morning, making morning calling setups most productive from below.

Rifle Season (Late October–November)

Hunting pressure pushes elk off accessible public-land edges quickly. Focus on the transition zone between Bitterroot National Forest land and private ranches — elk funnel through these corridors at dawn and dusk when moving between timber and feeding areas. The canyon bottoms and creek drainages east of US-93 concentrate elk during cold snaps.

Late Season Movement

Winter snow pushes elk to south-facing slopes at lower elevations. Valley-bottom hayfields adjacent to public land draw large groups of cow elk. Scout Block Management Areas for late-season access to private agricultural land that holds elk.

How to Hunt Elk in HD 100

HD 100's mix of public and private land rewards hunters who secure either Block Management Area access or position themselves on the public-land edges that border private ranches.

Canyon Calling — Archery

Focus calling on the east-side canyons entering from the Sapphire front. Blodgett Canyon and Bass Creek drainage offer concentrated bull activity during the rut. Walk quietly up-drainage at first light and use locator bugles from ridgeline saddles. Once you strike a bull, close to 80–100 yards in dense timber before cow-calling to draw him into bow range.

Timber Edge Ambush — Rifle

During rifle season, position on public-land timber edges that border private valley floor land before dawn. Elk leave bedding timber in the hills and cross into valley pastures — the timber-to-open transition is the kill zone. Saddles and creek crossings along these boundaries are natural funnels.

Block Management Area Access

Montana's Block Management Program (BMP) provides licensed hunters free access to enrolled private land during season. Check the current FWP Block Management guide for HD 100 parcels — valley ranches enrolled in BMP can offer outstanding late-season elk hunting with far less competition than adjacent public land.

Elk Success Rates

HD 100 elk success rates are moderate, consistent with valley-unit hunting pressure across southwest Montana. Rifle hunters see average success around 12–18% unit-wide, with hunters accessing interior Bitterroot National Forest drainages outperforming those limited to road-accessible public land. Archery success runs 6–10%. The mix of public and Block Management land creates variable outcomes — hunters with BMP access to valley ranches substantially improve their odds during late season.

General season cow-elk licenses in HD 100 are typically available over-the-counter for Montana residents. Non-resident hunters must apply for Big Game Combination licenses through FWP's drawing system, where demand for southwest Montana units is high. Bull elk opportunities in HD 100 depend on the current regulations — some years antlerless-only restrictions apply on general licenses. Check the current FWP regulation booklet for HD 100-specific license requirements before applying. The FWP Drawing Statistics portal at myfwp.mt.gov tracks annual applicant counts and quota levels.

Mule Deer Hunting in Unit 100

Mule deer in HD 100 occupy the sage-covered benches, rocky foothills, and lower forest edges of the Bitterroot Valley's east side. The Sapphire Mountain foothills along the eastern margin of the unit hold resident mule deer populations year-round, with bucks using the broken timber and rimrock terrain above the valley floor. General deer licenses cover both mule deer and whitetail in most of this unit — hunters should verify current FWP antler restrictions and license requirements before the season.

Where to Find Mule Deer in HD 100

Mule deer in HD 100 concentrate on the sage and bitterbrush-covered benches above the Bitterroot Valley floor and in the rocky foothills at the base of the Sapphire Mountains. Unlike whitetail deer that hold in the valley's riparian corridors, mule deer prefer the drier, open terrain of the breaks and ridgelines above.

Sage Flats and Rimrock Benches

The broken terrain east of US-93 between Stevensville and Hamilton features classic mule deer habitat — sage flats cut by dry coulees with scattered rimrock outcroppings above. Bucks bed in the rimrock during the day and feed on sage and bitterbrush in the flats at dawn and dusk. Glass these benches from elevated vantages in the early morning light.

Foothills Transition Zone

The ponderosa pine and Douglas fir transition zone at the base of the Sapphires holds mature bucks, especially as temperatures drop in October and November. Bucks use the timber for bedding cover and move into adjacent open draws to feed. Focus on draws with south-facing aspects that warm quickly in the morning sun.

Rut Timing

Mule deer rut peaks in mid-to-late November in HD 100. Bucks become more visible and cover more ground searching for does. Glass open terrain and ridge systems at first and last light during the rut — mature bucks that were nocturnal all season start moving during legal shooting hours.

How to Hunt Mule Deer in HD 100

HD 100 mule deer hunting centers on spot-and-stalk tactics over open to semi-open terrain. The sage benches and rocky foothills reward patient glassers who locate bucks before beginning a stalk.

Spot-and-Stalk from Elevated Vantages

Identify elevated vantage points along the bench edges east of the valley floor and glass methodically into the coulees and draws below. Spotting scope quality glass is essential for evaluating bucks at 500–1,000 yards before committing to a stalk. Approach from above and use terrain to stay out of the deer's sight line during the stalk.

Working Rut Bucks

During the November rut, mule deer bucks in HD 100 travel open ridge systems searching for does. Drive the valley-edge roads slowly at first light, stopping to glass each accessible ridge and draw. Once a rutting buck is located, circle wide to get the wind right and approach from a downwind angle using available cover.

Block Management Access

Check the FWP Block Management guide for enrolled private parcels in HD 100. Valley-edge ranches enrolled in BMP can provide excellent mule deer access on terrain that is otherwise locked up by private ownership.

Mule Deer Success Rates

Mule deer success in HD 100 averages in the 20–30% range for rifle hunters on general licenses, consistent with other Bitterroot Valley foothill units. Mule deer numbers here are supplemented by whitetail, and the deer-license structure generally allows either species. Trophy quality varies — the more rugged and less-pressured east-side terrain above the valley produces larger-bodied bucks than road-accessible public land near Hamilton.

Mule Deer Draw Odds

Search Montana Draw Odds

General deer licenses in HD 100 are available over-the-counter for Montana residents and through the non-resident drawing for out-of-state hunters. The license typically covers both mule deer and whitetail deer unless species-specific restrictions are in place for the current year. Antler-point restrictions (when in effect) can limit buck harvest to legal-sized animals — verify current FWP regulation requirements for HD 100 before purchasing a license.

Moose Hunting in Unit 100

HD 100 covers the area south of Glacier National Park along the North and Middle Fork Flathead River drainages within the Flathead National Forest. Shiras moose inhabit the extensive willow-lined creek bottoms, beaver pond complexes, and lodgepole regeneration areas in this classically productive northwest Montana moose country. The 100-00 limited moose permit is once-in-a-lifetime for Montana residents and among the most coveted tags in the state.

Where to Find Moose in HD 100

HD 100 offers exceptional Shiras moose habitat along the Glacier-adjacent drainages of the Flathead National Forest.

Willow Creek Bottoms and Beaver Complexes

Moose concentrate in the willow-choked creek bottoms and beaver pond areas throughout the North and Middle Fork Flathead drainages. These riparian corridors provide both browse and aquatic feeding. Bulls frequent active beaver ponds during the September rut, wallowing and feeding in shallow water.

Lodgepole Regeneration Areas

Post-fire lodgepole regeneration areas on the Flathead NF produce lush understory browse that draws moose consistently. The 2000s-era burn areas south of Glacier have created extensive young forest with ideal moose habitat. Scout these areas via satellite imagery before your season to identify productive drainages.

How to Hunt Moose in HD 100

Northwest Montana moose hunting in HD 100 rewards systematic scouting and patience in productive willow-bottom habitat.

Dawn Glassing on Willow Flats

Position above willow creek bottoms before first light and glass methodically. Moose feed in open areas at dawn before retreating to denser cover. A bull's antlers and back are often visible above the willow canopy — move quietly parallel to the bottom to confirm and close distance.

Rut Calling in September

During the September rut, cow calls and branch-raking on willows can draw responsive bulls. Set up at productive creek confluences or beaver pond edges with shooting lanes established. Calling is most effective in the first two hours after dawn and last hour before dark.
