The Great Island Path was a major Native American trail in the U.S. state of Pennsylvania that ran from the village of Shamokin (modern-day Sunbury) along the right bank of the West Branch Susquehanna River north and then west to the Great Island (near modern-day Lock Haven).
The path then continued "...up the ravine in Blue Hill and followed the present road for a few miles" along the ridge which is the border between Snyder and Union counties.
Then it curved to the river and passed through Shikellimy's town, which stood at the mouth of Sinking Run...".
Next the path "...followed the river along the base of the hills into White Deer valley..." where it turned west at what is now the village of Allenwood, following White Deer Hole Creek into Lycoming County "...along the south branch of the creek, near where the village of Elimsport is located, and over the mountain [i.e. North White Deer Ridge] into Nippenose valley through which it passed to the head thereof.
[1] The path then crossed into Clinton County "...over the hills and through a ravine in Bald Eagle Mountain to the river, where there was a fording to Great Island".
