 The French and Indian War (1754–63) led to the migration of many Native Americans westward to the Ohio River basin.On November 5, 1768, the British acquired the New Purchase from the Iroquois in the Treaty of Fort Stanwix, including what is now the Pine Creek Gorge east of the creek.The Purchase line established by this treaty was disputed, as it was unclear whether the border along "Tiadaghton Creek" referred to Pine Creek or to Lycoming Creek, further to the east.
