on each side of the Grand River
“…six miles deep from each side of the river beginning at Lake Erie and extending in that proportion to the head of the said river.”
The Proclamation of 25 October 1784 set these lands apart for the Mohawks and their posterity. The Nation has drawn the line six statute miles from the river’s banks, measured on the ground, and graded every stretch by how certain it is.
