32nd meridian west from Washington

The 32nd meridian of longitude west from Washington is a line of longitude approximately 109°02′48″ west of the Prime Meridian of Greenwich. In the United States of America, the meridian 32 degrees west of the Washington Meridian defines the western boundaries of the State of Colorado and the State of New Mexico and the eastern boundaries of the State of Utah and the State of Arizona.

On February 28, 1861, the Act Organizing the Territory of Colorado defined the western boundary of the new territory as the 32nd meridian of longitude west from Washington. The creation of the Colorado Territory moved the eastern boundary of the Territory of Utah west to this meridian.

Two years later on February 24, 1863, the Act Organizing the Territory of Arizona defined the eastern boundary of the new territory as the 32nd meridian of longitude west from Washington. This in turn moved the western boundary of the Territory of New Mexico east to this meridian.

These boundaries on the 32nd meridian of longitude west from Washington remained when Colorado became a state on August 1, 1876, Utah became a state on January 4, 1896, New Mexico became a state on January 6, 1912, and Arizona became a state on February 14, 1912. The point of intersection of these four states, known as the Four Corners, is the only place in the United States where four states touch.
