Overview
HD 420 is a small (77-square-mile) but varied district southwest of Lewistown that runs from the grain fields and willow bottoms along the Judith River west up into the timbered east face of the Little Belt Mountains to Bear Park Road. Its centerpiece for access is the Judith River Wildlife Management Area, backed by a piece of the Helena-Lewis and Clark National Forest higher up — together giving this district far better public opportunity (over half public) than its private-locked neighbors. Elk, whitetails, and mule deer all use the district, sliding between the ag bottoms and the mountain timber with the seasons.
Terrain
Grassy plains, willow-and-cottonwood creek bottoms, and ag fields along the Judith River on the east, rising steeply west into the rugged, timbered east front of the Little Belt Mountains.
Cover: Irrigated and dryland ag with willow and cottonwood on the valley floor, grass and sage benches, then thick Douglas-fir and ponderosa pine on the mountain slopes with grassy south-facing meadows.

Access
Uncommonly good public access for Region 4: the Judith River WMA and a corner of the Helena-Lewis and Clark National Forest together make up more than half the district, with old logging roads and trails opening the timber to hunters willing to hike. The plains bottoms and ag ground remain private ranch, where Block Management agreements and state trust sections fill in access. Note WMA seasonal closures that protect big-game winter range.
Managers: MT FWP Judith River WMA, USFS Helena-Lewis and Clark NF, private ranch + Block Management, MT DNRC state trust

Species notes
Rocky Mountain Elk
common qualityElk are the district's strength, using the Little Belt timber and the Judith River WMA winter range. Numbers are solid, though the district isn't a giant-bull producer; the WMA and national forest give real public elk opportunity.
- →Hunt the dark timber and grassy parks of the Little Belt east face early, then follow elk toward WMA winter range as snow builds
- →Work old logging roads on foot well back from the trailheads
- →Bugle and glass mountain parks at dawn during the rut
- →Time late-season hunts to the migration onto lower winter range
Whitetail Deer
abundant opportunityWhitetails are plentiful in the Judith River bottoms and adjacent ag fields, with good numbers but modest trophy potential.
- →Hunt river-bottom cover and field edges at dawn and dusk
- →Use the WMA and Block Management ground for legal bottom access
- →Target the November rut when bucks move in daylight
- →Slip the willow and cottonwood edges quietly
Mule Deer
common opportunityMule deer range the sage benches, foothill breaks, and open mountain timber between the bottoms and the high country, with average buck quality.
- →Glass foothill benches and burn or meadow edges at first light
- →Hike into the upper Little Belt basins for early-season bucks
- →Follow deer to lower rimrock and benches as snow arrives
Black Bear
common opportunityBlack bears work the timbered Little Belt slopes and berry pockets. The Little Belts are a solid island-range black bear range.
- →Glass green south-facing slopes and old cuts in spring
- →Hunt fall berry patches and mast pockets
- →Work the timbered draws and creek heads on the mountain
- →Confirm your target and be aware grizzlies are dispersing into central Montana island ranges
Pro tips
- →Play the two halves: public national forest and WMA on the mountain, Block Management and river access in the bottoms
- →Hunt elk high and early, then follow snow down toward the Judith River WMA winter range
- →Old logging roads off Bear Park Road are the key to hunting the Little Belt timber on foot
- →Check Judith River WMA seasonal closures before planning a late hunt
- →For a small district, the public land ratio makes 420 a good DIY option in private-heavy Region 4
Watch out for
- !Judith River WMA has seasonal winter-range closures — verify current dates before hunting
- !Plains bottoms are private ranch; confirm Block Management or landowner permission
- !Mountain roads and plains gravel turn slick or drift shut in snow
- !Grizzlies are dispersing into central Montana island ranges including the Little Belts — carry bear spray and hunt bear-aware
- !Steep, timbered Little Belt terrain demands fitness for backcountry access
Logistics
Utica and Hobson are the closest small stops; Lewistown and Stanford provide full fuel, lodging, and groceries within a short drive. Paved and gravel county roads reach the Judith River bottoms, while Bear Park Road and old logging roads climb into the Little Belt timber — expect rougher two-track and foot travel up high. Cell service is decent on the plains and drops off in the mountains.
