Black Mesa

Black Mesa is a mesa located in an area covering parts of the U.S. states of Colorado, New Mexico, and Oklahoma. It extends from Mesa de Maya, Colorado southeasterly 28 miles (45 km) crossing into the northeast corner of New Mexico, and ending in the Oklahoma panhandle along the north bank of the Cimarron River at its confluence with the North Carrizo Creek near Kenton. Its highest elevation is 5,705 feet (1,739 m) in Colorado. The highest point of Black Mesa within New Mexico is 5,239 feet (1,597 m). In northwestern Cimarron County, Oklahoma, Black Mesa reaches 4,973 feet (1,516 m), the highest point in the state of Oklahoma. The plateau that formed at the top of the mesa has been known as a "geological wonder" of North America. There is abundant wildlife in this shortgrass prairie environment, including mountain lions, butterflies, and the Texas horned lizard. (In Colorado, Black Mesa also refers to a summit in Gunnison County and a mountain pass in Dolores County.)

The plateau has been home to Plains Indians. In the late-nineteenth and early twentieth century the area was a hideout for outlaws such as William Coe and Black Jack Ketchum. The outlaws built a fort known as the Robbers' Roost. The stone fort housed a blacksmith shop, gun ports, and a piano. The present-day Oklahoma Panhandle area, which was then considered a no man's land, lacked law enforcement agencies and hence the outlaws found it safe to hide in the region. However, as new settlers arrived in the area for copper and coal mining and also for cattle ranching activities by grazing cattle in the mesa region, law enforcement became more effective, and the outlaws were brought under control. In more recent times, at least one person has claimed to have been abducted by extraterrestrial aliens at Black Mesa.
