San Bernardino National Wildlife Refuge
The San Bernardino National Wildlife Refuge is located on the U.S.-Mexico border in Cochise County, Arizona. Situated at 3,720 to 3,920 feet (1,130–1,190 m) elevation in the bottom of a wide valley, the refuge encompasses a portion of the headwaters of the Yaqui River, which drains primarily western Chihuahua and eastern Sonora, Mexico. The 2,309-acre (9.34 km2) ranch was acquired by the U.S. Fish and Wildlife Service in 1982 to protect the water resources and provide habitat for endangered native fishes.
