Montana Hunting Guide — Elk, Pronghorn

HD 420 covers the Pioneer Mountains in southwest Montana — a high, glaciated range straddling the Continental Divide with Beaverhead-Deerlodge NF ownership dominating. The 420-20 permit issues about 146 tags against 1,132 three-year applicants. Alpine cirques, talus slides, and timbered lower slopes define world-class elk habitat here.

Elk Hunting in Unit 420-20

Where to Find Elk in HD 420

Pioneer elk follow a classic western Montana alpine-timber seasonal pattern.

Big Hole Corridor

The Big Hole River side of the Pioneers hosts elk in the lower timbered drainages. FSR 484 along the Pioneer Scenic Byway opens multiple access points.

Alpine Summer Range

Through early September, bulls hold at 8,500+ feet in the cirques around Torrey Mountain and Crystal Park. Wallows and willow bottoms see consistent use.

Grasshopper Creek Fringe

The southern Pioneers drop into the Grasshopper Creek drainage — elk winter toward the lower sage-timber transition there.

How to Hunt Elk in HD 420

The Pioneers are one of Montana's most rewarding elk ranges for hunters willing to go high and stay there.

Alpine Bivy

Spike at 8,500+ feet during archery and hunt the high basins from camp. Bulls bugle from subalpine parks at dawn and evening.

Ridge-Glass in Rifle

Once snow pushes elk down, glass from the Pioneer Scenic Byway pullouts into the mid-elevation timber. Mornings and evenings are peak.

Grasshopper Creek End-Run

Late-season pushes take elk into the southern drainages — the Grasshopper Creek road system becomes productive by late November.

Pronghorn Hunting in Unit 420-20

HD 420-20 is a limited either-sex antelope permit covering the rolling sage and grassland country of eastern Montana's HD 420. The hunt delivers classic prairie pronghorn action across a mosaic of BLM, State Trust, and Block Management land. With roughly 884 applicants for 104 tags over three years, odds are reasonable for Montana pronghorn and the unit produces dependable mature bucks.

Where to Find Pronghorn in HD 420-20

Pronghorn in HD 420 concentrate along the sage-grass interface and around reliable water. Stock tanks and windmill-fed reservoirs anchor summer and early fall distribution.

Rolling Sage Bands

Bucks hold territories across the rolling bench country with mixed sage, grass, and cheatgrass flats. Glass from higher points to pick apart the draws.

Water-Centered Sign

In a dry October, focus on any stock tank or reservoir. Multiple bands often funnel to the same water source at midday.

How to Hunt HD 420-20 Pronghorn

Standard eastern Montana antelope tactics apply — glass, pick a buck, and close the distance using terrain.

Spot-and-Stalk

We mark bucks from a high vantage, then use the rolling coulees to disappear from their line of sight. Plan the stalk so the final 200 yards uses belly-crawling through sage.

Decoy During Rut

Late-season bucks respond to silhouette decoys. We set up within 150 yards of a dominant buck, show the decoy, and shoot off sticks when he closes.
