King George II established the current northern boundary in 1740, positioning it three miles from the Merrimack River. This decision shaped the territorial divisions that define the states today.
The boundary reflects how different states developed their own ways of organizing land and government. Visitors walking along the marker line notice how the landscape and local character shift between the two sides.
Granite markers placed along the boundary line help visitors locate the exact position where states meet. Following these markers from west to east provides a clear path for exploring the division.
