Meridian-Baseline State Park is a one hundred eight-acre historic preservation area on the Jackson-Ingham county line that protects the intersection of the Michigan meridian and baseline, key reference lines used to survey much of the state. It preserves the North Initial Point and South Initial Point, marking where two mismatched baselines meet the principal meridian, and is significant for Michigan’s surveying and land-division history rather than for large recreational development. Preservation efforts began in the nineteen sixties, and after added land created access from Meridian Road, the site opened to the public on October 12, 2015. A boardwalk added in 2016 improved access to the historic points.
