Unit 512
EL PASO
Foothill country between the Academy and I-25 with moderate forest and reliable water access.
Hunter's Brief
GMU 512 is a compact foothill unit nestled between the U.S. Air Force Academy and Interstate 25, featuring rolling terrain with scattered ponderosa and Douglas-fir forests. Elevations span from around 6,350 to 8,270 feet across accessible country with good road networks. Water is present via creeks and small reservoirs throughout, though availability varies seasonally. This is straightforward, relatively flat terrain with clear access points—practical country for hunters seeking established infrastructure without extensive backcountry travel.

Terrain Deep Dive
Landmarks & Navigation
Cathedral Rock stands as the most prominent landmark, easily recognized for orientation and glassing opportunities from distance. Monument Creek and its branches (including West Monument Creek) provide reliable navigation corridors draining the unit. Deadmans Lake and the series of smaller reservoirs—Reservoir Four, Lee Lake, and the numbered non-potable reservoirs—serve as both water sources and terrain anchors.
Stanley Canyon offers a major drainage system worth following for glassing and movement. Black Squirrel Creek and Smith Creek provide secondary water features and natural route-finding aids.
Elevation & Habitat
The unit spans modest elevation changes across medium-altitude foothill country, from roughly 6,350 feet in lower areas to just over 8,250 feet at higher points. Terrain transitions from open grassland and sagebrush benches to scattered ponderosa pine and Douglas-fir forests, with patches of oak scrub mixed throughout. The landscape is predominantly rolling rather than steep, creating mixed habitat where forest clearings meet brush-covered slopes.
Vegetation density increases with elevation, but no area becomes densely timbered—this is predominantly open-to-moderate forest interspersed with grassland parks.
Access & Pressure
This unit has connected road access via roughly 61 miles of maintained roads throughout the compact area, providing excellent entry points from surrounding communities. No major highways cross the unit, but I-25 proximity and Academy road systems mean easy logistics and staging from Colorado Springs. The straightforward terrain and connected access likely concentrate hunting pressure around established entry points and obvious valleys.
However, the unit's modest size and moderate forest cover mean pressure can be absorbed across different ridges and drainages. Early-season hunters may find quiet country by moving away from obvious access roads.
Boundaries & Context
GMU 512 occupies the land immediately south and east of the U.S. Air Force Academy's main boundaries in El Paso County. The unit is tightly defined: the Academy forms its northern and western borders, Interstate 25 marks the eastern edge, and the Academy's southern limits close it off. This is foothill terrain transitioning between the Colorado Front Range proper and the eastern plains.
The compact size and urban proximity mean easy access from Colorado Springs and surrounding communities, though hunting here requires understanding the Academy's restricted airspace and security perimeter.
Water & Drainages
Water is present but not abundant—a limiting factor in places. Monument Creek and its tributaries (West Monument Creek, Monument Branch) provide the most reliable flow, with perennial character in upper reaches. Deadmans Creek flows through the unit's western portions, though seasonal flow patterns vary.
Multiple small reservoirs—Deadmans Lake, Lee Lake, and the numbered facilities—supplement seasonal seeps and springs. Goat Camp Creek and other smaller drainages carry seasonal flow. Hunters should plan water strategy carefully; morning sources exist but midday access may require route planning around reservoir locations.
Hunting Strategy
GMU 512 historically supports elk, mule deer, white-tailed deer, pronghorn, moose, mountain lion, and black bear across its foothill habitat. Elk gravitate toward forested ridges and grass parks at mid-elevation; early season offers good opportunities in open areas before pressure pushes them into denser timber. Mule deer use both brushy foothills and scattered forest patches, particularly effective to hunt along ridge edges and canyon breaks.
White-tail populations prefer denser brush and creek bottoms. Pronghorn stick to open grassland benches. The moderate terrain and connected roads make this efficient country—plan to glass from ridge saddles, work creeks for water sources, and focus on the transition zones between forest and open park where multiple species converge.
