History, courtesy @swiftcarbonusa In July 1859, Government surveyors,Withrow and Todd, were charged with establishing the line demarcating Nebraska Territory on the north, and Kansas Territory on the south. This line was to follow the parallel of latitude 40° North, also known as the “Base Line”, and was to terminate at “the summit of the Rocky Mountains”, then the easterly line of Utah Territory. The survey crew navigated scorching plains and rugged mountainous terrain, traversing a distance of 345 miles in 55 days. This stone marker, set along the “Baseline” as surveyed in 1859, celebrates this historic survey party as well as all surveyors whose remarkable work aided in the organized westward expansion of the United States. 🤓📚🇺🇸 (at Baseline Road)
