Indiana was admitted by the U.S. Congress as the nineteenth state in 1816. Its Enabling Act moved the northern boundary ten miles north of the southernmost tip of Lake Michigan, providing direct access to the lake. The boundary was first surveyed in 1817 by William Harris. Disputes over the boundary with Michigan and Ohio continued until Michigan statehood in 1837. The Enabling Act of 1816 established Indiana's northern boundary, three miles north of here, as a line drawn through a point ten miles north of the southern extreme of Lake Michigan.
