Four Corners Monument
The Four Corners Monument marks the quadripoint in the Southwestern United States where the states of Arizona, Colorado, New Mexico, and Utah meet. It is the only point in the United States shared by four states, leading to the area being named the Four Corners region. The monument also marks the boundary between two semi-autonomous Native American governments, the Navajo Nation, which maintains the monument as a tourist attraction, and the Ute Mountain Ute Tribe Reservation.
U.S. Route 491
U.S. Route 491 (US 491) is a north–south U.S. Highway serving the Four Corners region of the United States. One of the newest designations in the U.S. Highway System, it was created in 2003 as a renumbering of U.S. Route 666 (US 666). With the 666 designation, this road was nicknamed the "Devil's Highway" because of the significance of number 666 to many Christian denominations, which is believed by some that 666 is the Number of the Beast. This Satanic connotation, combined with a high fatality rate along the New Mexico portion, convinced some people the highway was cursed. The problem was compounded by persistent sign theft. These factors led to two efforts to renumber the highway, first by officials in Arizona, later in New Mexico. There have been safety improvement projects in recent years, and fatality rates have subsequently decreased.
