Horse Creek Springs emerges at 75 degrees Fahrenheit in central Wyoming's high desert, flowing 218.9 meters from the nearest road at 6,873 feet elevation. The moderately warm water runs 33.9 degrees above ambient air temperature in Natrona County near Mills, accessible via a short walk through characteristic sagebrush terrain.

Location

The spring sits in high desert country at the eastern edge of Wyoming's Wind River Basin, where sagebrush-covered slopes give way to juniper and rocky outcrops. At 6,873 feet elevation, the landscape receives 13.4 inches of annual precipitation and 54.6 inches of snow, supporting sparse vegetation adapted to cold winters and hot summers. Horse Creek itself drains northward through the surrounding uplands toward the North Platte River system, carving shallow channels through sedimentary bedrock. The terrain shows typical basin-and-range topography with distant mountain views and wide-open sky.

Visit during late spring through early fall when access roads remain passable. Winter brings heavy snow that can close secondary roads and make the short walk challenging. Bring sturdy boots for walking across uneven sagebrush terrain. The spring sits on a mix of public and private land; verify access status before visiting. Combine with exploration of the surrounding Wind River Basin high desert ecosystem, or use Pete's Draw Campground 36.9 kilometers south as a base camp despite its 14-day stay limit and no-water policy.

History of Horse Creek Springs

The name derives from Horse Creek, the watercourse that drains this section of Natrona County. Historical records for this particular spring are limited, though the broader Horse Creek drainage supported ranching operations dating to the late 1800s. The area saw homesteading activity during Wyoming's settlement era, with ranchers utilizing the creek corridor for livestock operations that continue today.
