District 420, Montana

The district covers approximately 77 square miles with elevation ranging from roughly 4,400 feet on the valley floor along the Judith River to about 7,800 feet in the upper Little Belt Mountains. The eastern half is gently rolling to flat agricultural plain and prairie; the western half rises sharply into steep, heavily timbered mountain terrain. Relief on the forested USFS portion is abrupt, with dense ridgeline timber broken by grassy south-facing slopes and narrow drainages.

Primary vehicle access enters from the north via U.S. Highway 87/200; from Windham, turn south approximately 11 miles on paved Route 239 to the town of Utica, then continue south roughly 13 miles on a county road to reach the Judith River WMA and the USFS Judith Guard Station (elevation approx. 5,000 ft, Helena–Lewis and Clark National Forest, Judith Ranger District) along the north bank of the Middle Fork of the Judith River. A gravel road system runs approximately 9 miles along the north side of the Judith River from Utica toward Sapphire Village, then 1.5 miles west to the WMA headquarters. The WMA is closed to all recreational use December 1 through noon May 15 (source: FWP site detail lmsId=39753614); a travel plan map specifies which roads and parking areas are open during the hunting season. The National Forest portion provides the best sustained public access, with old logging roads through thick timber offering hiking-based penetration; motor-vehicle use is governed by the Helena–Lewis and Clark National Forest Motor Vehicle Use Map. Access to scattered state land parcels can be limited by surrounding private land. Block Management Areas (BMAs) in Region 4 — coordinated through FWP Region 4 HQ (406-454-5840) — provide additional access to private and isolated public land across Judith Basin County; BMA maps are required (free from FWP offices). The western boundary approximates Bear Park Road. Roughly 52.9% of the district is public land (Judith River WMA, USFS, state parcels combined). Cell service is unreliable throughout most of the district.

Lower elevations are characterized by long-grass prairie, dryland wheat fields, and willow-cottonwood riparian corridors along the Judith River and Sage Creek. The transition zone holds scattered ponderosa pine and sagebrush. Upper elevations on the Lewis and Clark National Forest support dense Douglas fir and ponderosa pine stands interspersed with intermittent grassy meadows on south-facing aspects. Old logging roads cross the timbered sections. The Judith River WMA contains riparian shrub-willow and grassland that serves as critical winter elk range.

Elk are present in significant numbers concentrated especially on and near the Judith River WMA during winter and spring. The combined HD 420/448 herd was counted at 1,082 animals in the 2025 aerial survey, placing the NE Little Belt Elk Management Unit at its population objective of 1,000–1,500. Elk are distributed across both the WMA grasslands and the timbered USFS sections. Mule deer occupy the prairie-foothill transition and timbered draws; whitetails are found primarily in the Judith River riparian corridor and along agricultural field edges. Pronghorn are present in the open plains portions and on/near the WMA (FWP WMA site lists antelope as a huntable species), but the HD 420 pronghorn population stands 46 percent below objective per the 2025 Region 4 big game forecast, indicating significantly reduced numbers. Black bear are present in the timbered sections of the Little Belts and are managed under a quota system in Bear Management Unit (BMU) 420. Mountain lion are present in the timbered mountain terrain. Moose are uncommon but may occur in riparian willow areas. The district is not a designated bighorn sheep or mountain goat unit.

1. WMA closure corrected to December 1 (closes end of day) through noon May 15, per FWP site detail lmsId=39753614 (draft stated Dec 2). 2. The 420-20 permit quota (80) and 448-00 B-license quota (150) are from the 2022 draft regulations; 2025-2026 quotas may differ — verify at fwp.mt.gov or FWP Region 4 HQ (406-454-5840). 3. The 2025 elk count of 1,082 combines HDs 420 and 448; the split between individual districts is not published. 4. Season dates updated to 2025 statewide reference (archery Sep 5–Oct 18; general Oct 25–Nov 30; muzzleloader Dec 13–21); always confirm with current FWP regulations. 5. General elk license in HD 420 is restricted to brow-tined bull or antlerless and is valid only during archery season; hunters wanting rifle/muzzleloader elk opportunity must hold the 420-20 permit or an applicable B-license. 6. Pronghorn 46% below objective confirmed via live FWP Region 4 forecast page; exact permit quotas not found in public-facing sources. 7. Hunter success percentages and annual harvest totals were not available in public-facing sources; paywalled on HuntScore. 8. The Lewistown News source returned HTTP 429 and could not be verified; removed from sources list. 9. Pronghorn confirmed present on/near WMA per FWP site (antelope listed as huntable species at lmsId=39753614).
