About

This rock monument was erected in 1938, 50 ft away from the original intersecting point mapped in 1857. A new plaque was embedded in 2004 in the correct spot. This is an easy stop at the end of a gravel road and you can high-five in  3 states at once! 

Not to be confused with the AR-MO-OK Tri-State Marker, or the tri-state markers for New York/New Jersey/Pennsylvania, Colorado/Nebraska/Wyoming, Pennsylvania/Maryland/West Virginia, or Delaware/Maryland/Pennsylvania.
