OKKAMO Tri-State Marker explained

OKKAMO Tri-State Marker is a monument showing the tripoint of Oklahoma, Kansas, and Missouri. It is located at an elevation of 1,016 feet^[1] (one source says 1,024 feet)^[2] and is about 300 feet north of I-44 and about 1000 feet east of the Downstream Casino and Resort, which is operated by the Quapaw Nation.

A marker built from native stone was erected in 1938 by the WPA, but it is located 50 feet to the west of the actual tri-point. A stand-on plaque was added in October 2004 at the actual site of the tripoint.^{[3] [4]}
