District 360, Montana

Steeply mountainous terrain ranging from approximately 4,800 feet in valley bottoms to over 11,316 feet on high peaks; Hilgard Peak at 11,316 ft is the highest summit in the Madison Range. Approximately 80% of public-land slopes are at or below 32 degrees. The upper elevations are largely above treeline with subalpine meadows and talus; mid-elevations support dense conifer forest; lower drainages open into valley grasslands and riparian corridors along the Madison and Gallatin River tributaries.

US Highway 191 (Gallatin Canyon road, Bozeman to West Yellowstone) provides the primary eastern access corridor, with multiple Forest Service roads and trailheads dropping into the Gallatin and Spanish Peaks drainages. US Highway 287 runs the western boundary along the Madison River and Ennis Lake, providing access from Ennis and the Madison Valley side. The district contains substantial portions of the Lee Metcalf Wilderness (total 254,288 acres), comprising four units in or adjacent to HD 360: Spanish Peaks (~76,000 acres), Taylor-Hilgard (~141,000 acres), Monument Mountains (~33,000 acres), and Bear Trap Canyon (~6,000 acres, BLM-administered). The majority of the district is walk-in or horseback access once off the highway corridors; horse access is strongly recommended for reaching remote backcountry. Public access is good in the Gallatin drainage portion of the district. Since 1993, access has declined on the Madison River side due to private land consolidation. Public land is approximately 40% of the district (436 sq mi footprint; 35% USFS, 1% BLM, 4% State per HuntScore 2021).

Lower and mid elevations support Douglas-fir, lodgepole pine, ponderosa pine, and subalpine fir with aspen pockets concentrated in creek bottoms. Higher elevations transition to subalpine fir, whitebark pine, and open subalpine parkland meadows above approximately 9,000 feet, giving way to alpine tundra and talus near the peaks. Riparian shrub corridors follow major drainages and provide concentrated deer and elk habitat, particularly in winter.

Elk are the signature big-game species and occupy the district in large numbers across two management sub-units (North and South). The population has fluctuated around FWP objectives and was pushed back within objective following intensive harvest combined with severe winters. Mule deer occupy the western (Madison Valley) side of the district in greater numbers than the eastern side, though populations remain below historic levels. White-tailed deer are present primarily on private lands on the western valley floors. Pronghorn antelope are present in the Madison Valley portions of the district; populations experienced a roughly 30% decline following severe winters in 2018-19 and subsequent years, leading to reduced doe/fawn license allocations. Black bears are widespread throughout the forested portions of the district. Mountain lions inhabit the rocky terrain. Grizzly bears have an established and expanding presence in the Madison Range. Gray wolves are present in the greater Yellowstone ecosystem adjacent to and within the district. Moose occupy riparian drainages in lower-elevation areas.
