McKinley County is on the western border of New Mexico. It is bordered by Cibola, Sandoval, Rio Arriba and San Juan Counties and it is also bordered on the west by Arizona. The county covers 5,455 square miles, making it one of the largest counties in New Mexico and the United States. Interstate 40 and U.S. Highway 491 are the lifeblood of the county and they meet in Gallup, the county seat.
The Navajo Indian Reservation covers about 60% of McKinley County and the Zuni Indian Reservation covers a sizable chunk of the county. Also, Ramah Navajo Indian Reservation covers a small portion of the county. This Indian reservation is actually a disjunct portion of the larger Navajo Reservation and votes in all tribal elections. The Ramah Navajos had a separate tribal government until the 1960s and they maintain a separate history from the larger Navajo Tribe. They were actually in this part of New Mexico before the larger tribe was. Another decent-sized chunk of the county is part of Cibola National Forest and a very small portion is part of Chaco Culture National Historical Park. Most of the land that does not belong to an Indian tribe or the federal government belongs to mining companies, principally coal mines. The county seat, Gallup, is almost completely surrounded by Navajo Reservation land.
