The northern boundary of the Indiana Territory was established by the 1809 Treaty of Fort Wayne between Gov. W.H. Harrison and the Indian tribes, with Miami Chief Little Turtle presiding. The line followed the shadow of an upright spear at 10:00 A.M. Historic Gosport is the only town directly on the line. The monument was designed and sculptured by noted Owen County artist and sculptor F.L. Hollis, on land made available by the David Gray family, descendants of Ephraim Goss, first settler in Gosport (Goss's Port) in 1818.
