Unit 140
Bob Marshall Wilderness Complex
Steep timbered valleys carved by the South Fork Flathead system, where dense forest meets connected trail access.
Hunter's Brief
Unit 140 is steep, forested country in the Mission Mountains west of the Continental Divide. The landscape transitions from lower river valleys through dense timber stands on mountain slopes. Access is connected via a network of Forest Service trails and some road access near Hungry Horse Reservoir. Water is reliable throughout the drainages. The complexity of the terrain and heavy forest cover means hunting requires deliberate planning and route-finding. Most hunters concentrate near trail heads and established camps.

Terrain Deep Dive
Landmarks & Navigation
Major peaks including Hungry Horse Mountain, Mount Orvis Evans, and Hash Mountain provide visual references from ridges and open terrain above the timber line. The South Fork Flathead River and its tributaries—Silver Run Creek, Solander Creek, and Wildcat Creek—form the primary drainages and travel corridors. Jewel Basin and Silver Basin offer open terrain for spotting or traveling.
Broken Leg Mountain and Pioneer Ridge provide natural navigation waypoints along the main divide system. Hungry Horse Reservoir anchors the western approach, visible from Highway 2 and useful for orientation. These features help hunters establish location in otherwise featureless timbered valleys.
Elevation & Habitat
The unit transitions from river-bottom riparian zones in the 3,000-foot range through dense lodgepole and Douglas-fir forests on the mid-elevation slopes, then opens into subalpine terrain as you climb toward the ridgelines. Heavy forest dominates the landscape—thick timber with limited understory characterizes most of the unit. Higher elevations feature alpine meadows and windswept ridgelines where trees thin considerably.
The steep topography means elk and deer use distinct elevation corridors, migrating seasonally between lower winter range and upper summer habitat. Travel through the timbered zones requires patience and careful navigation.
Access & Pressure
The unit features connected access via approximately 1,273 miles of road and trail network, though the density reflects the mountainous terrain. Highway 2 provides the main access corridor from the west near Hungry Horse and Coram. Forest Service trails numbered in the 80s and lower ranges provide primary access into the unit interior.
Most pressure concentrates near established trail heads and developed camping areas accessible from Highway 2. The steep terrain and dense forest mean that moving beyond the main trail systems quickly removes hunters from congestion. Well-connected doesn't mean well-traveled—the difficulty of the terrain filters out casual hunters. Strategic hikers who venture away from popular corridors find solitude.
Boundaries & Context
Unit 140 encompasses the southwestern portion of the Mission Mountains in Flathead County, Montana, bounded by the South Fork Flathead River and its major tributaries. The unit spans from the river corridors at roughly 3,000 feet elevation to steep ridgelines exceeding 8,600 feet. Hungry Horse Reservoir marks the western boundary near the town of Hungry Horse, providing geographic reference.
The unit is nearly entirely public land, with the Swan Divide forming part of the southern boundary. Access is defined by USFS trail corridors and Highway 2, which provides the primary approach from the western side.
Water & Drainages
Water is abundant throughout the unit. The South Fork Flathead River forms the primary drainage corridor, running north-south through the center of the unit with year-round flow. Major tributaries including Silver Run Creek, Solander Creek, Wildcat Creek, and several unnamed creeks provide reliable water at multiple elevations.
Baptiste Springs offers established water source. Smaller streams and springs are scattered throughout the drainages, though water availability decreases at higher elevations in dry summers. Most hunting camps are established near creek confluences or trail intersections with water access.
The moderate water availability badge reflects the complexity of this steep terrain—water is present but accessing it requires knowledge of drainage patterns.
Hunting Strategy
Unit 140 holds elk, mule deer, white-tailed deer, and mountain lions across its elevation bands. Elk use lower river valleys during winter and early season, then migrate to higher ridges and basins as snow melts. Mule deer favor the transition zones between dense timber and more open brush.
White-tailed deer inhabit the riparian corridors and dense forest edges. Glassing opportunities are limited by forest cover but available from ridgetop parks and alpine basins above timber line. Early season hunting focuses on water sources in the main drainages and high-elevation meadows.
Mid-season and rut hunting benefits from covering ground on the main trails and listening for bugles in the timbered valleys. Late season concentrates on lower elevations as snow pushes animals down. Physical fitness and route-finding skills matter more than luck in this terrain.
