The Bonanza Herd Management Area is located in northeastern Utah near the town of Vernal. Wild horses in this area generally originated from unclaimed ranch stock and/or from tribal horses from the Uintah-Ouray Indian Reservation. The Northern Ute Indians continue to have wild horses that roam free on adjacent tribal lands next to BLM managed Herd Area’s.
Topography in the region is undulating with elevations ranging from 4,900 to 6,100 feet in elevation. Vegetation types found within the HA are primarily salt desert shrub and sagebrush grasslands. Isolated pockets of Pinyon & Juniper trees offer wild horses areas of cover from the weather. Temperatures are extreme with summer highs in the upper 90’s and winter lows well below 0. The entire area of NE Utah (Uintah Basin) has winter climatic inversions at times that trap cold temperatures and fog for extended periods.
