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.
Four Corners, Maryland
Four Corners began as a 19th century agricultural community located at the crossroads on the Bladensburg and Colesville Roads. The community remained rural until the post-World War I building boom in suburban Montgomery County. Beginning in the late 1930s, Four Corners saw the development of Northwood Park, Woodmoor, Indian Spring Village, Indian Spring Terrace, North Hills of Sligo Park, and Fairway. These subdivisions expanded between 1945 and 1955 even as new ones, such as Northwood and Franklin Knolls, were constructed. The single-family house subdivisions that soon surrounded Four Corners had winding streets that formed an irregular grid in between major roads. Four Corners was largely developed by the late 1950s.
