Unit 170

Flathead Lake anchors the unit as a dominant geographic feature and navigation reference—its shoreline runs the entire southern boundary. Spencer Lake, Grayling Lake, and several smaller impoundments offer secondary orientation points. The Whitefish River and Stillwater River drainages provide navigational corridors; Rocky Creek, Walker Creek, and Schmidt Creek offer secondary drainage routes.

Foys Canyon and Brown Gulch create recognizable topographic features. The Flathead Valley itself serves as the primary open reference, with various populated places (Kalispell, Whitefish, Somers) marking settled areas where hunting access becomes restricted or complicated.

Nearly all terrain sits below 5,000 feet, with elevations ranging from around 2,900 feet on the valley floor to just under 5,000 feet on gentle foothills. The country breaks into distinct zones: open valley bottoms dominated by grassland and agricultural clearing, transition zones with scattered ponderosa and mixed conifers, and moderate-density forest on the higher foothills. Expect patchwork habitat reflecting the valley setting—wet meadows near water, drier sagebrush-grassland on benches, and timber becoming denser moving away from the lake.

The forest coverage is moderate overall, concentrated on north-facing slopes and higher ground.

The unit benefits from extensive road networks—over 2,000 miles of total roads provide high accessibility. US 2 and US 93 cross the unit; secondary highways and forest service roads create numerous entry points. This connectivity means hunters can access the country efficiently, but it also concentrates pressure along main routes and near road-accessible benches.

Valley-floor areas and vicinity of Flathead Lake see heavier use; more remote foothills drainages offer pressure relief. Private land ownership scattered throughout complicates access; hunters must verify boundaries carefully. The low terrain complexity rewards straightforward hiking and glassing near roads.

Unit 170 encompasses the lower Flathead Valley north and east of Flathead Lake, stretching from the Swan River drainage south of Bigfork west through Kalispell to the Whitefish area. The unit's southern boundary traces the north shore of Flathead Lake, while northern limits follow the Flathead River and adjacent ridgelines. The complex boundary weaves through established communities including Kalispell, Whitefish, and Somers, and follows US Highway 2 and US 93 as major reference lines.

This is working landscape country—agriculture, subdivisions, and lake recreation intermix with hunting opportunity.

Water is well-distributed across this lower-elevation unit. Flathead Lake dominates the southern boundary, while multiple smaller lakes including Spencer, Grayling, and Gilbert lakes offer reference points and potential water sources. The Flathead, Swan, and Whitefish rivers bound or cross the unit; the Stillwater River and its forks provide reliable interior drainages.

Numerous creeks—Walker, Rocky, Schmidt, Station, Sixmile—flow through the valley. Additional sloughs and wetland areas (Morning Slough, McWenneger Slough, various guts) support riparian habitat. Water scarcity isn't a concern here; seasonal reliability varies with creek size and valley position.

Unit 170 supports mule deer, white-tailed deer, elk, and mountain lion. Mule deer concentrate on open benches and forest edges at mid-elevations; white-tailed deer favor riparian timber and brushy draws. Elk historically use the valley's peripheral zones and foothills, with early season opportunities on high benches and late-season movement into lower drainages as weather pushes them down.

Mountain lion follow ungulate populations through timbered corridors. Early season favors glassing open foothills for mule deer; rut hunting targets riparian zones and timber edges where buck sign concentrates. Late season pushes animals lower into valley pockets and creeks.

Hunt away from main highway corridors and lake-access zones to avoid congestion.
