Unit 37

The Continental Divide runs as the unit's spine and serves as the primary navigation reference. Boreas Pass and Georgia Pass provide cross-divide access points and visual landmarks from distance. Dillon Reservoir, Green Mountain Reservoir, and Blue Lakes anchor water-based navigation and provide reliable glassing areas.

Grays Lake and the Eaglesmere Lakes complex sit in mid-elevation terrain. The Tenmile Range to the west and Williams Fork Mountains to the east frame the landscape and offer high-point vantage for reconnaissance.

This is consistently high-elevation country. Most terrain sits above 9,500 feet with numerous peaks exceeding 13,000 feet, including Meridian Peak and Crystal Peak. Alpine tundra dominates the highest ridges, transitioning into spruce-fir forests across mid-elevations and scattered timber on lower slopes.

The moderate forest coverage means mixed open parks and timbered sections create a patchwork habitat ideal for elk and mule deer migration routes. Seasonal snow cover is significant and affects accessibility throughout fall and spring.

Connected road infrastructure with 1,430 miles of total roads creates fair accessibility despite high-elevation terrain. I-70 provides major corridor access along the western boundary. Dillon and Breckenridge serve as primary staging areas with relatively easy highway access.

Road density supports distributed hunter pressure across multiple drainages. However, terrain complexity at 7.0/10 means distance from roads increases significantly once hunters leave developed corridors. Most pressure concentrates around accessible passes and low-elevation approach zones.

Unit 37 encompasses high-elevation terrain in Summit and Grand counties, bounded by the Colorado River on the north and the Continental Divide on the south and east. I-70 and the Eagle River drainage form the western boundary, while the Williams Fork River and Blue River drainages create the eastern edge. The unit straddles major watershed divides with Dillon Reservoir sitting as a central reference point.

Towns like Breckenridge and Dillon serve as gateway communities, though the unit's highest terrain sits well above established settlements.

Multiple reliable water sources make this a moderate-water unit. Dillon Reservoir and Green Mountain Reservoir provide consistent water access across broader areas. The Williams Fork River, Blue River, and Clinton Creek drain major sections with numerous tributary streams including Elliott Creek, Tenmile Creek, and Brush Creek systems.

High-elevation snowmelt feeds springs throughout, particularly Cold Spring and Iron Springs in accessible areas. Water presence supports hunter camps and reduces pack-in requirements across much of the terrain.

Unit 37 holds elk, mule deer, white-tailed deer, pronghorn, moose, and bear. Elk hunting requires vertical strategy—early season targets high-elevation parks above timberline, transitioning to mid-elevation forest drainages during rut, then lower slopes during late season. Mule deer utilize ridge systems and park transitions year-round.

Moose occupy willow bottoms in drainages like the Williams Fork system. High terrain complexity means successful hunters spend time beyond immediate road access; glass from high points, then hike into less-pressured drainages. Water sources provide natural funnels and camp locations in rougher country.
