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.
Fifth Circuit Four
The "Fifth Circuit Four" (or simply "The Four") were four judges of the United States Court of Appeals for the Fifth Circuit who, during the late 1950s, became known for a series of decisions (which continued into the late 1960s) crucial in advancing the civil and political rights of African Americans; in this they were opposed by fellow Fifth Circuit judge Ben Cameron, a strong advocate of states' rights. At that time, the Fifth Circuit included not only Louisiana, Mississippi, and Texas (the limits of its jurisdiction since October 1, 1981), but also Alabama, Georgia, Florida, and the Panama Canal Zone.
