Unit 56, Colorado

Elevation ranges from approximately 7,054 feet near Salida on the eastern valley floor to 14,269 feet at Mt. Antero. Terrain is steep to moderately steep throughout most of the unit, with 80% of public land having slopes of 32 degrees or less. The western portion consists of rugged alpine peaks and high basins of the Sawatch Range; the eastern edge transitions to the Arkansas River valley with flatter irrigated farmland. Three fourteeners dominate the western skyline: Mt. Antero (14,269 ft), Mt. Shavano (14,229 ft), and Tabeguache Peak (14,155 ft). The unit covers approximately 238 square miles.

The unit is approximately 70% public land: roughly 61% U.S. Forest Service (Pike-San Isabel National Forest, Salida Ranger District), 6% BLM (managed from the Royal Gorge Field Office), and 3% state. The remaining 30% is private, concentrated in the Arkansas Valley floor and along lower drainages — hunters must verify boundaries carefully as private and public lands intermix. Boundaries: North — Chalk Creek and Tincup Pass Road from St. Elmo; East — Arkansas River and CO Highway 291; South — U.S. Highway 50; West — Continental Divide. Primary access highways are US 50 (south corridor, Salida to Poncha Springs), CO 291 (east edge along the Arkansas), and US 285 north from Poncha Springs. County Road 250 off US 50 west of Poncha Springs leads to the Mount Shavano and Tabeguache Peak Trailhead (Forest Road 252), a key access corridor into the high-country Wilderness. The Chalk Creek drainage (CR 162 / Chalk Creek Road from Nathrop) provides northern access toward St. Elmo and high passes. Numerous primitive four-wheel-drive roads and ATV trails branch off maintained forest roads, and mining claim roads provide additional backcountry access throughout the range. Droney Gulch State Wildlife Area (2,949 acres at 7,765 ft elevation, GMU 56) lies north of Poncha Springs off US 285/CR 251 and is open to deer, elk, and small-game hunting; check current CPW regulations for open dates. The Collegiate Peaks Wilderness covers the northern and western high-country portions of the unit. Within designated Wilderness, mechanized and motorized access is prohibited — foot and horse travel only. The Colorado Trail crosses the lower eastern Wilderness margin and connects to trailheads. High-elevation forest roads (above approximately 11,000 ft) are typically inaccessible from late October onward due to snow; lower roads may have seasonal closures into early summer. Tire chains are recommended during 4th rifle season (November). Hunter recreational traffic (OHV and hiking) on lower trails and roads is described as heavy throughout the season.

Habitat transitions sharply with elevation: lower valley floors and eastern margins support sagebrush, native grasses, and riparian cottonwood along the Arkansas River and creek drainages. Mid-elevations (7,500–10,000 ft) hold oakbrush, scattered ponderosa pine, pinyon-juniper, aspen groves, and mixed-conifer slopes of spruce-fir interspersed with grass and wildflower parks. Upper-elevation terrain (10,000–12,000 ft) is dominated by spruce-fir forest and subalpine meadows. Above treeline, alpine tundra with grasses, wildflowers, and exposed rock characterizes the highest basins and ridgelines. Riparian willows line Chalk Creek, Browns Creek, and other drainages feeding the Arkansas River.

Elk are present throughout the unit and are most commonly encountered between 8,000 and 10,000 feet. During early archery season, bulls can range from 7,500 feet to above treeline; they move progressively lower with accumulating snowpack through late fall. Late-season elk (4th rifle and beyond) concentrate near valley bottoms (7,000–8,000 ft) and adjacent private ranchland. Rut occurs from early September through mid-October. The unit sees significant hunting pressure; elk that receive pressure tend to push onto adjacent private land, especially during later rifle seasons. Mule deer are found primarily in lower-elevation terrain on the east and south sides of the unit, particularly sagebrush and oakbrush slopes and the Arkansas Valley drainage. Deer move from high country down toward the Buena Vista corridor and US 24 during late fall and rut (late October through late December). Pronghorn occupy the sagebrush flats and lower Arkansas Valley grasslands; most pronghorn habitat is near or on private land, limiting public-land opportunity. Rut occurs early September through mid-October. Shiras moose are present; a CPW cow moose hunt is offered for the broader unit grouping 48/55/56/471/481/551/561. Moose tend to use riparian willow and alder corridors in drainages. Black bear inhabit the full elevation gradient from middle-elevation oakbrush and berry patches through spruce-fir forest. Peak pre-denning feeding activity occurs in late summer through September when bears shift dramatically into hyperphagia. Mountain lion are present throughout the unit in proportion to prey (deer) populations. Turkey occupy lower wooded drainages. Grouse, ptarmigan, and snowshoe hare are also present. No Rocky Mountain bighorn sheep hunting unit (S-prefix GMU) directly corresponds to this big-game GMU 56 — the nearby desert bighorn unit S56 is a geographically separate unit on the Western Slope near Grand Junction.

1. Public land percentage (70%: 61% USFS, 6% BLM, 3% state, 30% private) from HuntScore GIS-derived data — moderate confidence. 2. Harvest data (270 animals, 27% success, 725 total hunters) is from HuntScore for 2022 and covers all species combined; elk-specific figures could not be isolated. 3. OTC status for 2nd and 3rd rifle bull elk: GMU 56 was not listed among units moving to limited draw in 2026 (only GMUs 54, 55, 551 changed); confirm in official CPW brochure. 4. All 2026 season dates are statewide standard; consult official CPW brochure for any unit-specific hunt codes. 5. Pronghorn success rates (92% rifle, 5% archery) are moderate-confidence estimates from third-party aggregators. 6. Moose herd size and unit grouping (48/55/56/471/481/551/561) per GoHunt; applies to the broader grouping. 7. Unit size corrected to 238 sq miles per HuntScore data. 8.
