Unit 77
Boulder Ridge
Foothills country between Laramie and the Colorado border with scattered timber and reliable water sources.
Hunter's Brief
Unit 77 sits in the transition zone south of Laramie, mixing open foothills with patches of conifer cover across moderate elevations. A network of roads and irrigation infrastructure provides fair access throughout, though most land is private. Mule deer are the primary draw, using the sagebrush and timber mosaic seasonally. Water is more reliable here than surrounding high country—multiple reservoirs and creeks support hunting efforts. Expect moderate pressure, especially near highways and established access points.

Terrain Deep Dive
Landmarks & Navigation
Jelm Mountain and Ring Mountain anchor the higher terrain and serve as visual references across the unit. Sunrise Pass on Wyoming 230 provides a key route and landmark for navigation. Lower features like Fish Creek Rock help orient hunters within drainages.
The scattered reservoirs—Hutton Lake, Rice Reservoir, Lake George, and Willow Creek Reservoir among others—mark reliable water and often concentrate early-season deer activity. Multiple named creeks including Harney Creek, Spring Creek, and Woods Creek provide navigation corridors and additional water sources. These landmarks break the terrain into recognizable zones rather than serving as technical climbing objectives.
Elevation & Habitat
Elevations range from roughly 7,000 feet in the lower valleys to just under 10,000 feet on the higher ridges, with most terrain clustering in the 7,500- to 8,500-foot band. The landscape is predominantly open—sagebrush basins, grassland parks, and rolling terrain dominate the lower portions, with scattered ponderosa and Douglas-fir groves appearing on north-facing slopes and higher benches. Timber is sparse rather than continuous, creating a patchwork of cover and open country ideal for deer glassing and movement.
This open character means less dense forest, more visibility, and terrain that rewards both stalking and observation.
Access & Pressure
The unit benefits from over 200 miles of roads providing fair connectivity and logical access points. Most terrain lies within a 30-minute drive of Laramie, creating moderate baseline pressure, especially near highways and established pulloffs. However, the sparse public land percentage means access is fragmented—hunters must navigate around private holdings, and many of the best roads and water features sit on ranches.
This creates a dynamic where accessible terrain receives concentrated pressure while larger blocks of huntable country may see less traffic simply because legal access is limited. Road density is moderate, supporting vehicle-based access but not creating highway-like conditions.
Boundaries & Context
Unit 77 encompasses the foothills country immediately south and west of Laramie, bounded by U.S. 287 to the north and east, the Wyoming-Colorado state line to the south, and Wyoming Highways 10 and 230 forming the western perimeter near Woods Landing. The unit sits at the junction of the Laramie Range's eastern slopes and the Medicine Bow National Forest transition zone, roughly 20 miles south of Laramie proper. It's a moderate-sized block of terrain that bridges lowland prairie country with higher foothill systems, making it accessible from town yet offering distinct hunting terrain.
Water & Drainages
Despite the 'limited water' badge, this unit is actually well-supplied with water infrastructure and natural sources compared to surrounding high-country units. Multiple irrigation reservoirs and ditches demonstrate a long history of water management in the foothills. Hutton Lake, Rice Reservoir, and Willow Creek Reservoir are reliable, and seasonal reservoirs like Lone Tree and Goforth add options.
Named creeks including Harney, Spring, Woods, and Fox provide perennial or semi-perennial flow depending on season and snowpack. Springs like Willow Spring and Barrel Spring offer additional sources. Water availability is rarely a constraint here, making the unit relatively straightforward for logistical planning.
Hunting Strategy
Mule deer and white-tailed deer inhabit this foothills unit, with mule deer as the primary species and whites present in brushy creek bottoms and timber patches. Early season finds deer in the open sagebrush and parks at higher elevations; focus glassing on slopes with scattered timber cover where deer transition between bedding and feeding. As temperatures drop, movement intensifies along creek drainages and toward lower sagebrush.
The patchwork terrain rewards a mixed approach—glass open country from ridge vantage points, then move through timber corridors where they connect basins. Water sources like the reservoirs and creeks concentrate deer, especially in early season. Pressure concentrates near roads, so moving on foot away from obvious access points often improves encounters.
