The Seven Mile HMA is approximately 30 miles southwest of Eureka, Nevada, and totals 97,479 acres in size. This Herd Management Area is comprised of a long narrow valley nestled between the Toiyabe National Forest Monitor Range to the west, and the Antelope Range to the east. The lowest points of the valley are 6,300 feet in elevation, reaching 10,105 feet at Nine Mile peak in the Antelope Mountain Range. This narrow HMA serves as the transition between the Antelope Valley to the north, and the Little Fish Lake Valley to the south. The HMA stretches 31 miles long, and is only 8 miles wide at its widest point.
The current population is estimated to be 92 horses. An AML range of 60-100 wild horses has been established for both the USFS Butler Basin Wild Horse Territory and the Seven Mile HMA.
The only wild horse gathers to be completed within this HMA were conducted during July 2005 and February 2006 as part of the Fish Creek Complex gather. A total of 174 wild horses were removed from both the Seven Mile HMA and the Butler Basin Wild Horse Territory during these gathers. The Seven Mile HMA is managed with the Butler Basin WHT (managed by the U.S. Forest Service) to ensure that the year round habitat needs of the wild horses are met. Wild horses move up in elevation onto the Butler Basin WHT during the summer months, and winter in the lower elevations of the Seven Mile HMA, which remains clear of snow for a larger portion of the winter. Wild horses from the Seven Mile HMA also move north into the Fish Creek HMA, and south into the Little Fish Lake HMA and WHT.
Wild horses within the Seven Mile HMA are large in size with good conformation and comprised of a variety of colors.
