Unit 46

JEFFERSON/CLEAR CREEK/PARK

High-elevation forest and tundra straddling the Continental Divide with alpine lakes and challenging terrain.

Hunter's Brief

GMU 46 sits high on the Continental Divide, spanning timbered slopes and above-treeline terrain between 7,700 and 14,200 feet. Most of the unit is public land with good road connectivity for access staging, though much of the country itself is steep and technical. Multiple drainages and alpine lakes provide water, but the complexity of the terrain demands solid navigation skills. Early season offers flexibility across elevation bands; later seasons compress hunting into lower timbered zones as weather drives animals down.

Terrain Deep Dive

Landmarks & Navigation

Major summits including Mount Bierstadt, Mount Logan, Chimney Rock, and The Sawtooth serve as reliable navigation anchors and glassing vantages. Guanella Pass offers a recognizable high-point reference. Alpine lakes—particularly Josephine Lake, Abyss Lake, Square Top Lakes, and Frozen Lake—cluster in the upper basins and provide both water and navigation markers.

Elk Falls and Geneva Park give character to specific drainages. The network of named creeks (North Fork North Elk Creek, Beaver Creek, Willow Creek) traces major drainage systems down from the high country, useful for route finding and understanding water flow.

Elevation & Habitat

The unit is defined by its elevation—almost entirely above 9,500 feet, with significant area above 12,000 feet. Dense forest dominates lower drainages and mid-slopes, primarily subalpine spruce-fir giving way to limber pine and scattered aspen. Above timberline, rolling alpine tundra and meadows intersperse with rocky ridges and talus fields.

Mount Bierstadt and surrounding summits provide glassing platforms into productive mid-elevation terrain. The terrain transitions dramatically from forested canyons to exposed ridge country, creating distinct microhabitats for elk and deer across the elevation gradient.

Access & Pressure

Over 430 miles of road connectivity provides numerous entry points and reduces access pressure relative to pure wilderness units. Guanella Pass, Grant, and highway corridors enable vehicle staging to multiple trailheads, spreading hunter effort across several drainage systems. The road network is dense enough to allow relatively efficient access to lower and mid-elevation terrain, but the complexity of the actual topography (7.0 terrain complexity) limits how many hunters can effectively hunt the steeper upper country.

Pressure typically concentrates near roads and passes; significant solitude exists in the technical terrain away from established routes.

Boundaries & Context

GMU 46 occupies a substantial chunk of the Central Colorado high country, bounded by the Pike-Arapaho National Forest to the north and US 285 corridor to the east and south. The western boundary follows the North Fork of the South Platte River and the Continental Divide itself. The unit sprawls across portions of Clear Creek, Park, and Jefferson counties, encompassing some of Colorado's most recognized high-elevation terrain.

Access staging from Grant, Guanella Pass, and communities along the corridor makes this a well-traveled area, though the high terrain itself limits penetration.

Water & Drainages

Despite the high-elevation designation, water sources are limited but reliable where they exist. Multiple alpine and subalpine lakes concentrate in the upper basins—Josephine, Abyss, Square Top, and Frozen lakes are the primary cold-water sources. Lower elevations support perennial streams including North Fork North Elk Creek, Beaver Creek, and Willow Creek that drain toward the South Platte system.

Historical ditches (Hall Valley, Berrien, Wonder) indicate human water management but aren't reliable for field hunting. Water scarcity increases above treeline; hunters must plan access to known lakes and streams.

Hunting Strategy

Elk are the primary quarry, concentrated in timbered mid-elevations and transitioning to alpine parks during rut. Mule and white-tailed deer utilize the full elevation range with distinct seasonal movements. Early season offers high-elevation alpine access to both species; rifle season pushes hunting downslope as weather deteriorates.

Moose inhabit willow bottoms in lower drainages and park areas. Mountain lion and bear presence throughout adds context but aren't primary targets. The terrain complexity rewards hunters who glass from high points early, then work tactical creeks and parks during established seasons.

Steep terrain means careful foot travel and patience rather than aggressive hiking.
