Triangulation Station
1890
March 23, 2015
Triangulation station "TEKAMAH" was once located on a high hill on the southwestern part of Tekamah, Nebraska. When originally established in 1890, the monument consisted of a capped iron pipe over a lower stone. The position for this monument, as determined by adjusting the original latitude and longitude, is now within the area where an underground water storage tank was built many years ago. In 1934, USC&GS established their own triangulation station on the same hill which they designated "Tek". This monument is a standard bronze tablet in concrete and exists today. Also on this hill and to the north of "Tek" is a 2.5" brass cap in an iron pipe which was apparently established at an unknown date by the U. S. Army Corps of Engineers and designated "378". The monuments were recovered by Gene Thomsen, Kurt Luebke, and Jerry Penry.
