Unit 50
PARK
High Park County parklands with scattered timber, reliable water infrastructure, and moderate elevation relief.
Hunter's Brief
Unit 50 sits in the Park County basin country between U.S. 285 and U.S. 24, a landscape of rolling high parks interspersed with sparse timber and broken ridgelines. Elevations hover in the 8,000 to 11,500-foot band, creating distinct seasonal habitat zones. Well-developed ditch and reservoir systems provide consistent water access across the unit. Road infrastructure is solid with 918 miles of total road network, making access straightforward. The terrain complexity is low to moderate, favoring methodical hunters who work the open parks and timbered draws.

Terrain Deep Dive
Landmarks & Navigation
The Puma Hills and scattered ridgelines—Link Spring Ridge, Reinecker Ridge, Mexican Ridge—provide natural glassing vantage points across the parks. Key summits include Round Mountain, Eagle Rock, and Farnum Peak, useful for orientation and spotting game in the open country. The Basin features prominently as a central landmark.
Buffalo Creek and Fourmile Creek drainages cut through the unit as primary travel corridors and water sources. Milligan Lakes and Como Lake provide reference points for navigation in the upper country. The extensive ditch network (Antero Feeder, Park Ditch, Slater Ditch, and others) creates visible linear features useful for map navigation and understanding water flow patterns.
Elevation & Habitat
The unit spans a 3,600-foot elevation band from roughly 7,900 to 11,500 feet, creating distinct habitat tiers. Lower elevations feature open park meadows and sagebrush flats where pronghorn and early-season elk congregate. Mid-elevation slopes transition to scattered ponderosa and lodgepole stands with mixed shrub understory—primary mule deer and early elk country.
Upper reaches move into denser conifer stands with alpine parks interspersed among the timber. The median elevation around 9,300 feet places most hunting in the transition zone where multiple species overlap seasonally. Water availability and milder snow conditions at these elevations support year-round resident populations and seasonal migrations.
Access & Pressure
The 918-mile road network indicates substantial access infrastructure, making most of the unit reachable by vehicle. U.S. 285 and U.S. 24 bracket the unit as major approach corridors from I-25 and surrounding areas, suggesting moderate to heavy opening-week pressure in popular drainages. Forest Service roads and county roads penetrate most terrain, reducing true backcountry refuge.
Lower topographic complexity (4.4/10) and high road density mean standard hunting patterns converge on accessible drainages and parks. Success depends on working away from obvious road corridors into the scattered timber between parks. Early season crowds likely concentrate near established camping areas and reservoir access points.
Boundaries & Context
Unit 50 occupies Park County's central basin territory, bound by U.S. 285 on both north and west, CR 77 on the east, and U.S. 24 to the south. This rectangular block encompasses classic Colorado park-and-timber country characteristic of the South Platte drainage headwaters. The unit straddles the transition zone between lower elevation ranching country and higher montane terrain.
Hartsel and Antero Junction serve as reference points on the unit's edges, with Pike-San Isabel Village and Tarryall providing context for the broader landscape. The setting is high-elevation parkland rather than deep wilderness—working ranch and private land are interspersed with public hunting ground.
Water & Drainages
Water management infrastructure dominates the unit's hydrology. Multiple reservoirs—Antero, Buffalo Creek, Tarryall Ranch, Cline, and Tarryall—provide reliable surface water across the landscape. Fourmile Creek, Trout Creek, Buffalo Creek, and Jefferson Creek serve as perennial drainages supporting hunter access and game movement.
A network of named springs (Link, Elkhorn, Rishaberger, Willow, Baker, Berkey, Badger, Association) offer secondary water sources. The Antero Feeder Ditch and associated irrigation system indicate managed water delivery throughout the unit. This infrastructure makes the unit relatively water-rich compared to surrounding high parks, concentrating game use near reliable sources during dry periods.
Hunting Strategy
The unit supports elk, mule deer, white-tailed deer, pronghorn, moose, and black bear across its elevation zones. Early season (September) focuses on high parks and sparse timber where elk summer—ridge-top glassing for bulls transitioning between water and bedding. Mid-elevation mule deer inhabit the scattered conifer transition zone throughout fall.
Pronghorn concentrate in lower open parks and sagebrush flats, requiring glassing strategy rather than timber stalking. Rut hunting (October) pushes elk lower into mixed cover as temperatures drop and breeding activity increases. Late season finds elk and deer in the timbered drainages (Buffalo, Fourmile) where cover provides shelter.
Moose occupy willow bottoms near creeks and reservoirs. The accessible terrain favors spot-and-stalk over long backcountry ventures, rewarding patience in finding underhunted pockets between high-traffic zones.
