Unit 26, Colorado

GMU 26 spans an extreme elevation gradient, from roughly 5,300 feet near the Colorado River in the south to peaks exceeding 12,200 feet in the Flat Tops Wilderness on the unit's northern and western margins. The western portion is characterized by steep, rugged mountains with barren rocky slopes (Darby Peak, Flat Top Mountain), the central zone by moderately steep timbered mountains in the King Mountain complex (7,000–10,000 ft), and lower-elevation prairie benchlands in the east. Major drainages—including tributaries of the Colorado River—flow generally southward. The unit encompasses roughly 240 square miles with about 80% of public-land terrain having moderate to gentle slopes.

Primary highway access is Colorado State Highway 131, which runs north–south through the unit, passing through Toponas and Yampa (Routt County) and connecting south to Interstate 70 at Wolcott (Eagle County) and north to US Route 40 near Steamboat Springs. SH 134 (Flat Tops Trail Scenic Byway) branches west from SH 131 at Toponas, providing additional access toward the Flat Tops. County Road 5 (southwest of Toponas) and USFS Road 610 (to Stump Park) penetrate the interior. Key trailheads on the King Mountain BLM SRMA include King Creek, Stifel Creek, and Tepee Creek trailheads, all accessed via Highway 131 north of Wolcott. National Forest lands are administered by two forests: the White River National Forest (Rifle, Eagle-Holy Cross, and Blanco Ranger Districts) and the Medicine Bow-Routt National Forest (Yampa Ranger District for the northeastern margin). The Flat Tops Wilderness prohibits motorized and mechanized vehicles; access is foot and horse only. The King Mountain BLM Special Recreation Management Area (~12,000 acres, 7,000–10,000 ft elevation) is likewise designated for foot and horse travel only—no OHVs—and is managed by the BLM Colorado River Valley Field Office. Upper roads (above roughly 9,000 ft) typically become seasonally impassable by the third rifle season (early November) due to snow. Private land constitutes approximately 50% of the unit, concentrated in the lower valley bottoms, creating a checkerboard pattern that hunters must navigate carefully.

Vegetation follows a classic elevational sequence. At lower elevations (below 8,000 ft) sagebrush flats, pinyon-juniper woodlands, and Gambel oak (oakbrush) dominate the south-facing slopes and valley floors. The mid-elevation band (8,000–10,000 ft) transitions to aspen groves interspersed with open parks, lodgepole pine, and mixed conifer. North-facing slopes and upper elevations (above 10,000 ft) support dense dark timber—Engelmann spruce and subalpine fir—typical of the Flat Tops. The Flat Tops plateau itself grades into open subalpine meadows and, at the highest elevations, alpine tundra and rocky fellfields above treeline. Riparian corridors of cottonwood, willow, and alder line the major creek drainages at lower elevations.

GMU 26 supports a diverse big-game assemblage anchored by a substantial Rocky Mountain elk herd (part of the White River Elk Herd complex, one of the largest in Colorado). Elk use the high-elevation Flat Tops Wilderness and dark-timber basins as summer range and begin migrating to mid- and lower-elevation oakbrush and sagebrush winter range as snow accumulates, typically by late October through November. The rut occurs primarily in September, with bulls active in the wilderness and timber zones. Mule deer follow a similar altitudinal migration—summer range in higher parks and aspen, winter range on lower sagebrush-oakbrush benches. Shiras moose are present and growing in number, concentrated in riparian willows and high-elevation basins; large bulls are observed annually in the Flat Tops backcountry. Black bears are well distributed across oakbrush and aspen zones and especially active in late summer during hyperphagia on berry and oak mast crops. Pronghorn antelope occupy lower-elevation sagebrush and grassland flats in the eastern portions of the unit; populations are near the high end of management objectives. Mountain lion populations shadow deer and elk migrations. Wild turkey occupy lower-elevation oakbrush and pinyon-juniper transition zones along creek drainages and valley floors. The regional bull-to-cow elk ratio was approximately 17:100 in recent years.

1. Harvest statistics (total harvest, hunter success %, licenses issued) for individual species in GMU 26 are not publicly accessible without CPW login or paid services; HuntScore figures (368 total animals, 20.5% success for 2022 across all species) are cross-species aggregates—treat as directional only. 2. OTC elk status for residents (archery and rifle 2nd/3rd) confirmed by multiple sources; nonresident archery elk west of I-25 moved to draw-only as of 2025—verify current hunt codes in the official CPW 2026 Big Game Brochure. 3. 2026 season dates (muzzleloader Sept 12-20, Rifle 1st Oct 14-18, Rifle 2nd Oct 24-Nov 1, Rifle 3rd Nov 7-15, Rifle 4th Nov 18-22) are from the CPW 2025-2029 five-year season structure; always verify against the current CPW brochure. 4. Antler point restriction (4 points or 5" brow tine on one antler) confirmed for GMU 26. 5. The new pronghorn muzzleloader hunt for GMU 26 in 2026 was confirmed; specific hunt dates and codes were not publicly available as of research date—check CPW 2026 brochure. 6. Public land: HuntScore reports 50% (30% USFS, 19% BLM, 1% State, 12% Wilderness); GoHunt reports 49.5%—reported here as 50% rounded. 7. Road 610 accesses Stump Park (not Sump Park as sometimes misspelled). 8. King Mountain SRMA is managed by BLM Colorado River Valley Field Office, not USFS.
