Unit 17, Colorado

Elevations range from approximately 7,800 ft at the North Park basin floor near Walden to 12,951 ft at the high peaks of the Continental Divide and Rabbit Ears Range. The basin floor (roughly 8,000 ft average) is flat to gently rolling sagebrush-grassland and agricultural ground. The mountain margins transition through steep, rocky slopes, high alpine basins, and windswept saddles from 9,000 to 12,000+ ft. The unit is generally windy and prone to early-season snow; 4WD is recommended in inclement weather.

Primary highway access via US-40/CO-14 (over Muddy Pass) from the south, CO-125 running north-south through the center of North Park (the main valley corridor through Walden), and CO-14 entering from the east over Cameron Pass. Jackson County Road 28 provides east-west access across the southern portion of the unit to MacFarlane Reservoir State Trust Land. Routt National Forest (Parks Ranger District, 100 Main St, Walden CO; 970-723-2700; front office temporarily closed — call ahead) is the dominant public land manager. BLM Kremmling Field Office administers additional parcels. MacFarlane Reservoir State Trust Land (2,880 acres, 18 miles south of Walden on HWY 125 to CR 28, then 2.1 miles west to parking lot) is open August 15 through end of February only; a valid hunting or fishing license is required for access. Motorized access is allowed on the two-track route north of CR 28 for one mile to a designated parking area only; beyond that point access is foot or horseback only. Motorized vehicles on National Forest land are closed October 15 through the end of regular big-game rifle seasons (game retrieval allowed on designated routes 10 a.m.–2 p.m. and 30 min after sunset to midnight). Mt. Zirkel Wilderness lies to the west; Never Summer Wilderness to the southeast — both are non-motorized. Approximately 36% private land is present, predominantly along the valley floor as agricultural/ranch land; big game can move onto private ground with no public access.

The valley floor supports sagebrush, buckbrush, bitterbrush, and native grassland with agricultural hay meadows; willows line streams and creek bottoms (prime moose habitat). The surrounding forest transitions from aspen and lodgepole pine at mid-elevations to Engelmann spruce and subalpine fir on upper slopes and ridgelines. North-facing slopes hold dense lodgepole pine, Douglas fir, and blue spruce stands. Riparian corridors (North Platte River tributaries, Illinois River headwaters) support cottonwood and willow. Buffalo Creek and Lost Creek drain through narrow brush-choked canyons.

Elk are distributed throughout the unit and tend to summer at higher coniferous elevations in the Rabbit Ears Range and surrounding mountains, moving to lower elevations as snow accumulates and hunting pressure builds. Mule deer also summer in timber and migrate early — few deer remain in North Park by January. Pronghorn antelope are present on the sagebrush basin floor year-round but tend to be most concentrated on private/agricultural land. Shiras moose were introduced to North Park in 1978 when CPW transplanted 24 animals from Wyoming and Utah; the North Park area now supports what CPW describes as the densest moose population in Colorado, managed at approximately 500–600 animals across the North Park region (GMUs 6/16/17/161/171). Moose concentrate along willow-lined stream corridors. Black bear inhabit timbered drainages. Mountain lion are present. Hunters must be absolutely certain of target identification — moose/elk misidentification is a documented concern and CPW has conducted extensive education campaigns on this topic.

1. Harvest and success data sourced from CPW 2017–18 Northwest Region Hunt Guide (2016 season data). 2. Antler restriction for elk confirmed: 4 points on one antler OR brow tine ≥5 inches required in GMU 17 for all seasons — this was missing from the original draft. 3. Archery elk OTC status updated: resident archery elk remains OTC in GMU 17; nonresident archery elk is now draw-only (west of I-25, effective 2026). 4. Moose introduction details confirmed: 24 animals from Wyoming and Utah transplanted in 1978. 5. MacFarlane Reservoir access details verified from CPW page: open Aug 15–end of Feb; motorized to 1 mile north of CR 28 only; foot/horseback beyond. 6. Specific Forest Service road numbers (106, 715, 700) removed — could not be verified from authoritative sources. 7. Parks Ranger District phone (970-723-2700) and address (100 Main St, Walden CO) confirmed; front office temporarily closed — call ahead. 8. Pronghorn 2026 second rifle doe hunt confirmed for GMU grouping 6/16/17/161/171. 9. OTC bull elk change (GMUs 54/55/551) does NOT affect GMU 17.
