Black Mesa (Oklahoma, Colorado, New Mexico)

Black Mesa is a term applied to several mesas located in the states of Oklahoma, Colorado, and New Mexico. Generally, "Black Mesa" refers to a mesa capped by a layer of dark-colored volcanic rock, typically basalt or another dark igneous rock. This dark caprock contrasts with the lighter colored sedimentary layers below, giving the mesa its characteristic "black" appearance from a distance.

In Oklahoma, Black Mesa refers to the prominent mesa in the Oklahoma Panhandle, located in Cimarron County. This Black Mesa is the highest point in Oklahoma, rising to 4,973 feet (1,516 meters) above sea level. The area surrounding Black Mesa in Oklahoma is a biologically diverse region, supporting various plant and animal species adapted to the high plains environment. It is also a popular destination for hiking, stargazing, and geological study. The Oklahoma Black Mesa Nature Preserve protects a significant portion of the mesa and its surrounding landscape.

Similar formations are found in Colorado and New Mexico, though they may be locally referred to by other names as well. These mesas share the common geological characteristics of a dark caprock overlying sedimentary layers, often formed through volcanic activity that occurred millions of years ago. The resistance of the volcanic rock to erosion has allowed these mesas to stand above the surrounding landscape. These mesas provide valuable habitats and serve as important landmarks within their respective regions. The geological processes that created these Black Mesas contribute to a rich geological history in the southwestern United States.
