 Sixth principal meridian

The Sixth Principal Meridian is a north-south line designated for surveying purposes in the United States. It serves as a reference point for the Public Land Survey System (PLSS), which is used to systematically divide and describe land in certain areas of the U.S. The Sixth Principal Meridian runs primarily through the states of Nebraska, Kansas, and a portion of Colorado. It was established in the mid-19th century and is significant in the context of land measurement and ownership in the central United States.
