1. Colorado's Northeast Corner Marker
Property of the State of Colorado
The Organic Act creating the Territory of Colorado was signed by President Buchanan on February 26, 1861. The act carved from the territories of Kansas, Nebraska, Utah and New Mexico the 104,247 square miles that became the 38th state in 1876. The original survey establishing this boundary point was completed by Oliver N. Chaffee on October 7, 1869 and recorded on a six foot limestone shaft set in a circular earth mound centered at the intersection of the 25th meridian west from Washington, D.C. and the 41st parallel north from the equator. At its time of replacement in 1976, the broken shaft, originally inscribed on the north, 25 W.L.; east, Nebraska; west, 41 N.L.; and south, 68 M. 79 CH. and 59 LKS. (the distance between the 40th and 41st parallels) was badly eroded. When resurveyed, the new inscription cited the now standard Greenwich reference for the longitudinal measurement.
Erected 1977 by The State Historical Society of Colorado and the People of Sedgwick County through the Mrs. J.N. Hall Endowment
