Mount Ellen

Mount Ellen ranks No. 29 among the 57 ultra-prominent peaks in the contiguous United States, rising 11,522 feet in the Henry Mountains of remote southern Utah with 5,842 feet of clean prominence. It is the highest summit in the Henry Mountains and Garfield County on BLM-managed public land reached by dirt roads south of Hanksville. Most hikers use the Bull Creek Pass to Mount Ellen North Ridge route for 3.8 miles round-trip with 1,250 feet of gain on Class 1 terrain.

The Henry Mountains are exceptionally remote, with minimal infrastructure, limited development, and dirt-road access that shapes every Mount Ellen attempt. The peak stands directly adjacent to Mount Ellen Peak, 11,506 feet and just 16 feet lower, making it possible to traverse between both summits in a single outing. The range is often described as the last major mountain range in the contiguous United States to be formally mapped by Euro-American survey parties, with Powell's expedition reaching the area in the 1870s. A free-ranging bison herd inhabits the Henry Mountains region.

Bull Creek Pass to Mount Ellen North Ridge

The standard route follows a worn hiking route from Bull Creek Pass trailhead (10,500 ft), ascending the north ridge through rolling alpine terrain. The route climbs approximately 1,250 feet over 3.8 miles round-trip in 2–4 hours. The path is generally clear and well-used in normal snow-free conditions, passing through tundra and scattered rock to a false summit near 11,400 feet. The true summit lies beyond and is distinguished by a mailbox registry. These distance and gain figures assume road access to Bull Creek Pass; starting from Lonesome Beaver Campground adds approximately 12.4 miles round-trip and 3,250 feet of elevation gain. An optional traverse to Mount Ellen Peak adds approximately 400 feet of descent and re-ascent with 30–45 minutes of additional Class 2–3 scrambling on steep rocky terrain.

The Henry Mountains are accessed via remote dirt and rock roads from Hanksville, Utah. Bull Creek Pass trailhead is located approximately 1 hour south of Hanksville and requires a vehicle capable of handling dirt/rock road surfaces. Roads may wash out during precipitation or snowmelt. Check with the BLM Hanksville-Henry Mountains Field Office or local recreation guides for current road conditions before departure.

Key Landmarks

• Lonesome Beaver Campground (8,215 ft)
• Bull Creek Pass trailhead/parking (10,500 ft)
• False summit (11,400 ft)

No technical climbing skills are required on the standard route in normal snow-free conditions. The route is a non-technical hike, but parties should be comfortable with high-altitude hiking, exposed weather, and basic route awareness near the false summit. The optional Mount Ellen Peak traverse is more difficult than the standard Mount Ellen route and includes Class 2–3 scrambling. Afternoon thunderstorms are common from July through August, with over 30% of annual precipitation falling during summer months as heavy thunderstorms. The upper ridge is fully exposed with minimal shelter; lightning is a serious hazard. Early-morning alpine starts or afternoon descents are standard practice for avoiding electrical storms. Road access to Bull Creek Pass can be blocked by snow into late June or even early July in heavy snow years. If the road is impassable, hiking is feasible from Lonesome Beaver Campground, adding approximately 12.4 miles round-trip and 3,250 feet of elevation gain.

High-altitude exposure with minimal tree cover creates significant UV hazard; sunscreen is essential.
