San Antonio Mountain is a free-standing volcanic peak in Rio Arriba County, New Mexico. With an elevation of 10,908 feet, San Antonio Mountain is the highest peak within the Taos Plateau volcanic field, the largest volcanic field within the Rio Grande Rift valley.
The mountain lies just outside a northwest boundary of the Rio Grande del Norte National Monument. It lies within the Carson National Forest and is administered by the U.S. Forest Service rather than the Bureau of Land Management.
It is called "Bear Mountain" by Tewa-speaking peoples in the Rio Grande valley, and is known as the mountain of the north in their cosmology.
San Antonio Mountain is one of several volcanic peaks within the 7000 square kilometer Taos Plateau volcanic field, a region of tectonic uplift within the Rio Grande rift valley. Other nearby peaks include Ute Mountain (2,600 feet), Cerro de la Olla (9,475 feet), Cerro del Aire (9,023 feet), and Cerro Montoso (8,655 feet). San Antonio Mountain is both the highest peak in the region and possesses the greatest relief, but it is shorter than the highest peaks in the surrounding ranges: Grouse Mesa (11,403 feet) in the Tusas Mountains to the west, and Wheeler Peak (13,161 feet) in the Sangre de Cristo Mountains to the east. However, because it stands alone, San Antonio Mountain is a distinctive feature that can be seen from as far as 60 or more miles away in southern Colorado and northern New Mexico.
San Antonio Mountain has a base diameter of five miles, and rises dramatically from the surrounding sagebrush plains of the lower San Luis Valley.
