Where
Dunkard Creek near Mount Morris, Pennsylvania

In October 1767 the surveying party's Iroquois guides refused to proceed west of Dunkard Creek, near Mount Morris, having reached the border of their lands with the Lenape.

In October 1767, at Dunkard Creek near Mount Morris, Pennsylvania, nearly 244 miles west of the Delaware, Mason and Dixon's Iroquois guides refused to go any further, having reached the border of their lands with the Lenape, with whom they were engaged in hostilities. This refusal effectively ended the westward progress of the survey. The legacy claim that a Mohawk chief halted the party is not supported by the supplied passages, which attribute the halt to the Iroquois guides generally.
