Tri-State Marker
Colorado - Nebraksa - Wyoming
The Tri-State Monument marks the spot where Colorado, Nebraska, and Wyoming meet.
The Monument was first established by Oliver N. Chaffee, U.S. Astronomer and Surveyor,
August 17, 1869, at the intersection of the Forty-First Parallel of North Latitude with the
Twenty-Seventh Degree of West Longitude, several hundred feet away from where Congress
intended it to be. Nevertheless, it served as the official boundary between the three states.
The Monument was rehabilitated in 1981 by Art Hendrickson and Howard Kieler.
In 1997, federal, state, and local organizations coordinated additional preservation.
In July 2004, the Kimball Rotary Club and a local Boy Scout constructed a surrounding
fence and gave the monument a face-lift by placing an engraved metal plate with
Colorado, Nebraska, and Wyoming indicating their border around the marker.
Stay on the designated trail -
between the fence and transmission line posts, except around
water tanks - all other areas are considered to be trespassing.
Foot traffic ONLY.
No overnight camping.
Pack out your trash.
Travel at your own risk - rattlesnakes in the area.
Watch your step - trail has an uneven surface.
Trail is not regularlly maintained.
Be respectful of private property.
Thank you for visiting the Tri-State Marker!
In memory of Howard Kieler, Art Henrickson, and Dan Kinnison.
Signs provided by the Kimball Rotary Club.
