The Thirty-Second Parallel North is a circle of latitude that is 32 degrees north of the Earth's equatorial plane. It runs across several countries, including the United States, Mexico, and parts of Asia and Africa. This parallel is significant in geography and is often used as a reference point for mapping and navigation. In the United States, the Thirty-Second Parallel North passes through states like California, Arizona, and New Mexico. It is also notable for its historical context, as it was used in the 19th century to define certain territorial boundaries, including those related to the Missouri Compromise.
