District 555, Montana

The district spans approximately 790 square miles across dramatically varied terrain, ranging from roughly 4,100 feet in the arid canyon lowlands to 8,400 feet on the Beartooth plateau. The Pryor Mountains feature long, deep limestone canyons, rocky cliffs, and broad grassy plateaus. The eastern Beartooth front rises steeply above the Clarks Fork Yellowstone River valley. Lower elevations transition to sagebrush-covered high desert with sparse vegetation, rock outcrops, and cactus. The 2021 Robertson Draw fire burned approximately 30,000 acres on the east face of the Beartooth Mountains, eliminating nearly all conifer and sagebrush cover in that burn footprint.

Primary highway access is US Highway 212 (the Beartooth Highway) along the western boundary; the highway is typically open from Memorial Day through mid-October and climbs to nearly 11,000 feet. A second approach uses Montana Highway 310 south from Laurel to Warren, then approximately 20 miles of gravel road into the Pryor Mountain canyons. The Pryor Mountains are accessed via two primary routes: Pryor Mountain Road from the west and Crooked Creek Road from the south; roads within the Pryors are generally poor and require high-clearance vehicles. The district falls within the Custer Gallatin National Forest (Beartooth Ranger District, Red Lodge; 406-446-2103), which administers Forest Service roads including Forest Roads 2140 (Picket Pin Road) and others. Bear Track, Timberline, Silver Run Plateau, and Bridger Trailheads provide foot and pack access into higher terrain. The eastern portion of the district overlaps Bighorn Canyon National Recreation Area (NPS), where hunting is permitted with awareness of restrictions near developed recreation sites. Large portions of the remaining district are BLM land open to public access. An estimated 68% of the district is public land. Private-land inholdings exist in the Beartooth foothills; some elk congregate on private ranchland in lower-elevation hayfields, limiting access for public-land hunters. FWP Block Management Area listings (Region 5) may provide private-land access for some parcels seasonally.

Vegetation varies sharply by elevation. Upper Pryor Mountain plateaus support Douglas-fir and ponderosa pine forest broken by long grassy ridges and wildflower-covered meadows. Mid-elevation slopes transition to mixed pine and sagebrush. Lower canyon country consists of sparse sagebrush scrub, native bunchgrass, rock, and cactus. River bottoms and drainages support riparian cottonwood/willow stringers. The 2021 Robertson Draw burn created thousands of acres of post-fire forb and grass that attracted a major elk influx from Wyoming by 2023; this early-successional habitat supports high-quality forage but minimal cover.

Mule deer are the primary big-game species and are found throughout the district, with the best populations in the Pryor Mountains at mid- to upper elevations. White-tailed deer occur in lower numbers, concentrated in river bottoms and cottonwood drainages. Elk populations grew substantially following the 2021 Robertson Draw fire: a 2023 fall estimate placed 600–800 animals along the Beartooth foothills, up from a pre-fire management objective of 150–200 and a 2022 survey count of 166 (below the 150–250 objective). The 2025 FWP count recorded 230 elk in HD 555 (Absaroka Elk Management Unit), within the 150–250 objective range and status At. Some animals migrate seasonally from Wyoming's Bennett Creek area. Elk in the burned area have limited hiding cover, which affects their behavior during hunting seasons. Black bear numbers are locally notable; the Pryor Mountains' varied habitat supports them. Mountain lion presence is documented in the Pryor Mountains. Pronghorn are present at lower elevations on the eastern and southern portions of the district. Wild horses roam the Pryor Mountain Wild Horse Range (BLM-administered), which overlaps portions of the district but is not a huntable species. Rocky Mountain bighorn sheep are documented in the Pryor Mountains and are managed under separate hunting districts. CWD has been detected in white-tailed deer in HD 555 at approximately 18% prevalence (N=11, 95% CI 5%–48%) as of the 2024 CWD report.
