Unit 47
EAGLE/PITKIN
High alpine terrain above the Frying Pan and Roaring Fork rivers with steep ridges and interconnected drainages.
Hunter's Brief
Unit 47 is rugged, high-elevation country straddling the Continental Divide between Eagle and Pitkin counties. Steep mountainous terrain with dense forest transitions to alpine parks and meadows above timberline. Access is good via a connected road network, though terrain difficulty keeps pressure moderate. Limited reliable water outside major drainages requires planning. This is complex country best suited to hunters comfortable with elevation gain and navigation in steep timber.

Terrain Deep Dive
Landmarks & Navigation
Key summits for orientation and glassing include Red Mountain, Mount Yeckel, and Mount Nast, which anchor major ridge systems. Thimble Rock provides a distinctive landmark for navigation. The Williams Mountains spine offers elevated vantage points.
Granite Lakes, Midway Lake, and the Fryingpan Lakes cluster provide reference points in the high country. South Fork Pass and Midway Pass offer natural saddle crossings. The Frying Pan River drainage and South Fork Fryingpan River provide major corridor routes through the unit—critical for navigation in this steep terrain.
Elevation & Habitat
Terrain spans from mid-elevation river valleys near 6,600 feet to alpine summits exceeding 14,000 feet, with most country concentrated above 9,500 feet. Lower elevations feature mixed conifer forest and aspen groves along the main river drainages. Mid-slopes transition to dense subalpine spruce-fir forest with increasing steepness.
Upper elevations break into alpine parks, tundra meadows, and exposed ridgetops. Multiple named parks—Bessie, Van Horn, Twin Meadows, Slab Park—punctuate the high country, providing natural meadows and travel corridors through otherwise continuous forest.
Access & Pressure
The unit benefits from over 429 miles of road infrastructure, suggesting reasonable trailhead access despite the steep terrain. Populated places including Nast, Norrie, and Thomasville cluster at lower elevations and serve as staging points. The connected road network means hunters can access multiple entry points, distributing pressure across drainages rather than concentrating it at single choke points.
However, steep slopes and dense forest limit total accessible acreage—pressure concentrates in established park meadows and valley bottoms rather than spreading across high ridges.
Boundaries & Context
Unit 47 occupies steep mountain country in the Elk Range and Williams Mountains region. The Frying Pan River forms the northern boundary while the Roaring Fork River anchors the west side, with the Continental Divide running along the eastern edge. Colorado 82 marks the southern limit.
The unit encompasses portions of Eagle and Pitkin counties, centered around the Midway and Nast drainages. This is substantial terrain with significant relief, bounded by major river systems that define access patterns and serve as natural corridors for both game and hunters.
Water & Drainages
Despite listed alpine lakes and reservoirs, reliable water is sparse outside major creek systems. Sawyer Creek, Hunter Creek, and the South Fork Fryingpan River are consistent water sources following main valleys. Numerous smaller creeks—Deeds, Granite, Midway, Lily Pad—flow through drainages but may be unreliable late season.
Midway Lake and Ivanhoe Lake offer dependable water near trails. The interconnected ditch system (Salvation, Tie Camp, Red Mountain) indicates historical water management but offers limited hunting-season value. Upper elevation hunters must plan around creeks and high lakes.
Hunting Strategy
This is primarily elk and mule deer country, with moose present at higher elevations and white-tailed deer in lower river bottoms. Elk use the alpine parks seasonally, moving between high summer range and lower-elevation timber in fall. Early season hunting targets elk in high parks like Bessie and Van Horn.
Rut hunting focuses on rutted-up bulls working the parks and adjacent timber. Mule deer follow similar elevation patterns. The steep terrain and dense forest reward glassing from ridgetop vantage points rather than ground stalking through thick cover.
Water scarcity makes established creeks and lakes critical gathering points for game, especially late season.
