Kansas-Nebraska Border

A cast iron marker marks the 40th Parallel--the dividing line between Kansas and Nebraska. The marker was placed at this location May 8, 1855 by Charles Manners and Capt. Thomas J. Lee of the U.S. Army Corp of Engineers. The marker is 500 to 600 lbs., hollow, 1" thick, with a 16" square base. It was cast in St. Louis, MO in 1854. The 40th Parallel played an important roll in the Kansas-Nebraska Act and demarked disputed areas--slave and free--precipitating the American Civil War.

The 40th Parallel, the 6th Principal Meridian, is the longest baseline in the U.S., marking state boundaries to the Colorado-Utah border.

Anyone interested in seeing the marker in person must be willing to hike upward--150 feet vertically--on a trail maintained for that purpose. Using switchbacks, a cleared path and handrails, one can climb to the marker which sits atop the Missouri River Bluff on Highway 7 just west of the Missouri River. See more details
