Ellicott's Rock, Ellicott Rock Wilderness

Ellicott’s Rock is a survey marker placed in 1811 by Andrew Ellicott as part of his survey to resolve the boundary dispute between the U.S. states of Georgia and North Carolina. The boundary dispute involved a brief armed conflict between the two called the Walton War, followed by an 1807 survey that Georgia refused to accept. Ellicott, hired by Georgia, undertook a new survey that confirmed the earlier line. He engraved a large rock in the Chattooga River with "N-G", standing for North Carolina - Georgia. The location had been prescribed in part in 1787 by the Treaty of Beaufort, though the river was not named explicitly, but rather as a then-undiscovered tributary of the Savannah River between Georgia and South Carolina. The nominal latitude of 35°N was later specified by the U.S. Congress. ()
