Visitor Tips and News About Only International Boundary Marker Within the U.S.
This is the only remaining International boundary marker in the United States. It was placed as a marker between the United States of America and the Republic of Texas in 1840. A commission was appointed to establish and mark the boundary, which had been in dispute since the early 1700s between France and Spain. It was still in dispute when the U.S. made the Louisiana Purchase from France in 1803. The U.S. and Spain agreed that the disputed strip would be neutral territory until an agreement could be reached by the two nations. The strip soon became a refuge for outlaws and deserters seeking to avoid the laws of any government.[Gerald D Massey, 07/08/2012]
