100th Meridian Marker
Cozad, NE
This marker stands near the 100th meridian, the line of longitude that became a milestone in the building of the transcontinental railroad. In 1866 the Union Pacific reached the 100th meridian in central Nebraska, a moment celebrated with a widely publicized excursion for dignitaries and investors, and the meridian itself came to symbolize the edge of the arid West where farming gave way to open range.
