Raton Mesa is the collective name of several mesas on the eastern side of Raton Pass in New Mexico and Colorado. The name Raton Mesa or Mesas has sometimes been applied to all the mesas that extend east for 90 miles (140 km) along the Colorado-New Mexico border from Raton, New Mexico and Trinidad, Colorado to the Oklahoma panhandle. These include Johnson Mesa, Mesa de Maya, and Black Mesa.
The highest point of Raton Mesa, Fishers Peak, is located in Las Animas County, Colorado. The highest part of the mesa (4,183-acre (16.93 km2)) was made a National Natural Landmark in 1967. Raton mesas are volcanic in origin caused by lava flows which solidified into basalt. Over time the softer sedimentary rock surrounding the basalt eroded leaving several distinct large elevated tablelands with precipitous sides.
Raton Mesa is part of the Raton Basin a coal and natural gas producing region.
Interstate Highway 25 through Raton Pass, 7,834 feet (2,388 m) in elevation, separates the foothills of the Sangre de Cristo Mountains to the west from the mesa country on the east. For this article, Raton Mesa is defined as the area east of Interstate 25 between Trinidad, Colorado and Raton, New Mexico, approximately 19 miles (31 km) south to north, and extending eastwards about 13 miles (21 km). Within this area are three distinct mesas separated by deep canyons: Fishers Peak Mesa in Colorado, with a maximum elevation of 9,633 feet (2,936 m), Bartlett Mesa, mostly in New Mexico, with a maximum elevation of 8,900 feet (2,700 m), and Barela/Horseshoe/Horse Mesa, straddling the Colorado/New Mexico state line, with a maximum elevation of 8,757 feet (2,669 m). The elevations at the foot of the mesas are 6,000 feet (1,800 m) or higher.
