Late in 1831, when Wisconsin was still in Michigan Territory, Lucius Lyon, U. S. Commissioner on the survey of the northern boundary of the State of Illinois, set a post and erected a mound of earth 6 feet square at the base and 6 feet high at a point 1/2 mile east of here to mark the intersection of that boundary and the 4th Principal Meridian. Wisconsin public land surveys began here in 1832 and were completed up north in 1867. In 1832-33, Lyon surveyed 16 townships in southwest Wisconsin, opening the Territory for settlement, and in 1833 Michigan Territory honored this veteran surveyor by electing him its Delegate to Congress. Although the post and mound were obliterated long ago by fence and power line construction, this point is preserved by a concrete surveyor's monument. From this Point of Beginning came the survey and mapping of every section corner monument in the state, the boundaries of each county, city, village, township, farm, and lot, and the position of roads, lakes, and streams.
