During the 1900's to the 1940's, the Army Remount Service was active in a portion of the Antelope/Antelope Valley Complex. Periodically, the Army would release animals in the wild to upgrade their stock. The released stallions were mainly thoroughbreds or Morgans. A few draft blood lines were introduced to develop a hardier strain of horse to pull wagons and heavy artillery. As a result, the wild horses found in the complex are hardy and sound. They possess a variety of colors with variations from white to black, but most are sorrels and bays. There are about 362 different species of wildlife in the Complex including mule deer, sage grouse, blue grouse, eagles, and hawks.
Location: The Pancake Complex is located approximately 30 miles west of Ely, Nevada, or 80 miles northeast of Tonopah, Nevada, within White Pine and Nye Counties. The complex consists of the Sand Springs West and Pancake Herd Management Areas (HMAs), Jakes Wash Herd Area (HA) and Monte Cristo Wild Horse Territory (WHT). The BLM Ely District Office administers the Pancake HMA and Jakes Wash HA.
Size: The area consists of 849,613 acres of BLM land and 309 acres of a mix of private and other public lands for a total of 849,922 acres.
Topography/Vegetation: The area is within the Great Basin geographical region, which is one of the largest deserts in the world. The Great Basin physiographic region, characterized by a high, rolling plateau underlain by basalt flows covered with a thin loess and alluvial mantle. On many of the low hills and ridges that are scattered throughout the area, the soils are underlain by bedrock. Elevations within the Complex range from approximately 5,000 feet to 11,000 feet. Annual precipitation ranges from approximately 5 inches or less on some of the valley bottoms to 20 inches on the mountain peaks. Most of this precipitation comes during the winter and spring months in the form of snow, supplemented by localized thunderstorms during the summer months. Temperatures range from greater than 90 degrees Fahrenheit in the summer months to minus 20 degrees in the winter. The area is also utilized by domestic livestock and numerous wildlife species.
