Mason Dixon Line

High Quality Content by WIKIPEDIA articles! The Mason-Dixon Line was surveyed between 1763 and 1767 by Charles Mason and Jeremiah Dixon in the resolution of a border dispute between British colonies in Colonial America. It forms a demarcation line among four U.S. states, forming part of the borders of Pennsylvania, Maryland, Delaware, and West Virginia. In popular usage, especially since the Missouri Compromise of 1820 the Mason-Dixon Line symbolizes a cultural boundary between the Northern United States and the Southern United States.
