Unit 471 is a Grand County subunit covering the Williams Fork drainage and the country between Hot Sulphur Springs and Kremmling—Middle Park country with the Williams Fork Mountains rising to the south. Elevations run from about 7,800 feet on the Colorado River corridor near Parshall and Hot Sulphur Springs to 12,000 feet on the Williams Fork ridges. The terrain is classic Middle Park high-country: sagebrush parks and willow-bottom riparian along the Colorado River and the Williams Fork itself, climbing through aspen and lodgepole pine on the mid-slopes (significant beetle-kill complications—standing dead lodgepole is a real factor in stalking and pack-outs), into dense subalpine spruce-fir and alpine meadow systems above 11,000 feet, and bedrock-and-tundra ridges on the highest reaches. The Williams Fork Reservoir sits in the unit and is a notable water and recreation feature. Mule deer and elk both produce well; black bear is good in the aspen-and-oakbrush transition; moose have been increasing in the willow bottoms. Arapaho-Roosevelt National Forest covers the higher country with the Vasquez Peak Wilderness on the southern boundary edge. Significant private deeded ranchland covers the valley floor along the Colorado River and lower Williams Fork. US-40 cuts east-west through Hot Sulphur Springs and Parshall; the Williams Fork Road climbs south into the timber. Hot Sulphur Springs has gas, lodging, and the historic hot springs; Kremmling at the CO-9 / US-40 junction is the bigger working town for fuel, food, and processors; Granby east is full service. Cell service is fair on US-40 and gone in the timber. Pressure is moderate—the unit is overshadowed by the more famous Routt and Eagles Nest country.
