Unit 16

Russell Glacier, Milk Creek Glacier, and Jefferson Park Glacier mark the alpine zone and provide navigation anchors for high-country hunting. Major water features including Blue Lake, Clear Lake, and Triangle Lake serve both as water sources and orientation points. Ridge systems like Devils Backbone, Horseshoe Ridge, and Galena Ridge offer glassing opportunities and travel corridors through the forested midcountry.

The Palisades and Big Cliff provide dramatic reference points visible from lower elevations. Multiple waterfalls including Eagle Creek Upper Falls, Yocum Falls, and Middle North Falls mark major drainages and drainage confluences where elk concentrate.

The unit is overwhelmingly low-elevation country with nearly 97% of terrain below 5,000 feet, creating a landscape dominated by mixed conifer forest interspersed with open prairie valleys. Dense forest covers roughly two-thirds of the unit—ponderosa pine and Douglas fir dominate lower elevations while true fir and hemlock increase on cooler, moister aspects. Open prairie flats and meadows break the forest canopy, particularly in the valley bottoms and higher benches.

The small percentage of higher terrain above 5,000 feet includes alpine meadows, rocky summits, and glacier-fed basins that provide distinct late-season habitat and escape terrain for mountain goats and sheep.

Over 16,700 miles of road network provide exceptional accessibility with a density of 5.0 miles per square mile—making nearly every drainage reachable by vehicle. Highway systems including major routes and over 1,000 miles of maintained roads create multiple entry points and staging opportunities. This connectivity means pressure can be significant in accessible pockets, but the sheer size allows dispersal.

Private land ownership at 36% creates checkerboard patterns requiring map study, particularly in valley bottoms and lower elevations. Successful hunters should expect to move beyond initial access points and penetrate higher ridgeline country where fewer people travel despite easy road access.

Unit 16 encompasses over 3,300 square miles of the Willamette River watershed and western Cascade Range in Oregon. The unit stretches from the low-elevation Willamette Valley floor and riverine canyons at near-sea level up to the high alpine summits exceeding 10,000 feet. Major populated areas including Silverton, Foster, Lacomb, and Evansville anchor the valley portions, while higher country is defined by cliff bands, glaciers, and alpine lakes.

This is working landscape where extensive road systems, irrigation infrastructure, and private land corridors weave through otherwise continuous public terrain.

Water is abundant throughout Unit 16 with the Santiam River system and its tributaries providing perennial flow, plus extensive networks of creeks and springs. Major named streams include Mist Creek, Jordan Creek, Mad Creek, and Cotton Creek that drain the midcountry into lower valley systems. Higher elevations feed glacier-melt creeks and alpine lakes providing reliable water for high-country hunting.

The Willamette River itself forms the western boundary, creating massive water infrastructure including reservoirs, irrigation canals, and lock systems. Seasonal water patterns are less critical here than in drier units—springs, creeks, and lakes are dependable throughout the hunting season.

Elk are primary quarry across multiple elevations—lower-elevation animals in dense timber require close-range stalking and persistence, while higher-country elk use glacier basins and alpine meadows seasonally. Mountain goats and sheep occupy cliff terrain and alpine ridges, requiring glassing from distance and patient approach to rocky country. Black bear and mountain lion are present throughout, with bears concentrated in productive berry drainages and higher forests.

Pronghorn are possible on prairie flats in lower valley sections. Early season hunting targets higher ridges and basins before snow, while mid-season focuses on mid-elevation forests as animals migrate down. Late season concentrates on remaining low-elevation refugia.

The terrain complexity requires understanding aspect, drainage systems, and private land boundaries rather than just road access.
