Unit 19, Colorado

Elevation spans from approximately 4,850 feet along the eastern edge near Fort Collins to 12,702 feet in the southwestern alpine peaks. The terrain grades from prairie and foothills on the eastern margin through deep canyons (notably the Cache la Poudre River corridor) and forested mid-elevation ridges to high alpine basins and peaks along the Continental Divide near Cameron Pass (10,276 ft). Roughly 80% of the terrain has slopes of 23 degrees or less, making much of the unit accessible by foot, but steep canyon walls and wilderness interiors present significant backcountry challenges.

Primary vehicle access corridor: State Highway 14 (Poudre Canyon Road) runs the length of the unit from Fort Collins west through the Cache la Poudre canyon to Cameron Pass (10,276 ft) and into North Park. This is the sole paved artery through the mountain portion of the unit. The Canyon Lakes Ranger District (Roosevelt National Forest, headquarters in Fort Collins) administers approximately 650,000 acres; much of the western two-thirds of GMU 19 falls within this district. Key Forest Service roads branching off SH-14 include those accessing Pingree Park, Long Draw Reservoir, and numerous canyon drainages. State Highways 34 and 36 provide additional southern and eastern access into the foothills fringe. Three wilderness areas totaling approximately 85,975 acres are walk-in or horse-only: Comanche Peak Wilderness (66,791 acres), Neota Wilderness (9,924 acres), and Cache la Poudre Wilderness (9,258 acres; largely burned in 2012). State areas with vehicle access include Lory State Park (2,492 acres) on the eastern margin and Poudre River SWA (395 acres); Bliss State Wildlife Area (351 acres) is also present. The eastern half of the unit is predominantly private land and blocks access to some public land parcels. Post-fire flooding has caused culvert blowouts and debris-flow damage on several Forest Service roads; current road conditions should be confirmed with the Canyon Lakes Ranger District before accessing. Twenty-one Roosevelt NF campgrounds operate seasonally. North Park OTC elk units (GMUs 6, 16, 17, 161, 171) are approximately 35 minutes west of Cameron Pass.

Below approximately 6,000 feet: plains grassland and open prairie. Foothills zone (6,000–7,500 ft): juniper/pinyon woodland, ponderosa pine, oakbrush, and sagebrush. Mid-elevation (7,500–9,500 ft): ponderosa pine transitioning to dense lodgepole pine, aspen stands, and Douglas fir. Upper elevations (9,500–11,500 ft): Engelmann spruce and subalpine fir dominate elk summer range, with scattered aspen parks. Alpine zone above ~11,500 ft: grasses, wildflowers, willow thickets in drainages, and low tundra shrubs. The 2020 Cameron Peak Fire burned large portions of the lodgepole and mixed-conifer zones, producing extensive snag fields, early-succession shrub habitat, and increased elk forage in burned areas. The earlier 2012 High Park Fire (87,284 acres, Cache la Poudre corridor) also altered portions of the unit.

Elk and mule deer are the primary big game species. Elk summer range generally concentrates between 9,500 and 11,500 feet; bulls move into high alpine basins through summer and begin the rut as early as the first week of September, typically running through early October. Elk migrate down from high country ahead of winter snowpack, shifting to lower mid-elevation drainages and the foothills-prairie transition. Mule deer follow similar altitudinal patterns, using oakbrush, sage, and pinyon-juniper zones during winter. Post-Cameron Peak Fire snag fields and regenerating shrubs are actively attracting elk and deer to burned areas as forage quality improves. Shiras moose are present and hunted in GMU 19 (draw-only, very limited tags), found in riparian willow and spruce-fir zones near the upper Cache la Poudre drainage and Long Draw area. Black bear inhabit the mid-elevation forests and are drawn to berry crops and the burn-edge transition zones in summer and fall. Mountain lion are present throughout. Rocky Mountain bighorn sheep are present in the adjacent Never Summer Range (sheep unit S19 overlaps the southwestern portion of GMU 19; draw-only, very limited tags). Wild turkey and blue grouse are also present.

Unit-level elk/deer harvest statistics were not obtainable from publicly accessible CPW reports. Tag quotas are null because the 2026 Big Game Brochure PDF could not be parsed. Bighorn Sheep unit S19 (Never Summer Range) geographically overlaps the southwestern corner of GMU 19 but is a separate administrative unit with its own draw. OTC bull elk availability for 2nd and 3rd rifle seasons should be verified in the current CPW Big Game Brochure. All season dates reflect the 2025–2029 CPW season structure framework; confirm exact 2026 dates in the published brochure. The HuntScore composite figure (412 animals / 2,011 hunters / 15.3% success, 2022) covers all species combined and is not species-specific.
