The Carrizo Mountains (36°50' N, 109°7'W) is a small, mostly circular mountain range 15 to 20 km (9 to 12 miles) in diameter located on the Colorado Plateau in northeastern Arizona. The range is about 20 km (12 mi) southwest of the Four Corners. The highest summit, Pastora Peak, is 2,869 m (9,413 ft) in elevation, whereas elevations on the surrounding plateau are near 1,800 m (5,900 ft).
The mountains are within the Navajo Nation. Teec Nos Pos, Arizona, the closest community, is adjacent at the northern foothills, on Teec Nos Pos Wash, from Pastora Peak, about 5-mi miles to the north from the mountain's perimeter; Teec Nos Pos had about 800 inhabitants in the 2000 census.
