The Genesee river cuts deeply through sedimentary layers here. These lands used to belong to the Seneca indians. Not far from here was the land of a white woman that had grown-up as a Seneca. She cultivated it with some of her mixed blood sons. Her name was Mary Jamison. She was captured in a frontier Pennsylvania farm in the late 1700's by a warring party of French and indians. Her original family was massacred. She was given to the Seneca by the French to replace a dead warrior. Her life, and that of the Indian tribes fate is a tragic one. The Seneca were technologically in the stone age. This becomes SHOCKINGLY vivid when you look at their stone tools. The male Seneca were warriors and hunters. When they could no longer do this they got hooked by the white mans liquor. Mary's middle son - very much a Seneca - killed her two other sons that had inherited more white traits.
