The fruitful grounds of the Iroquois Indians was called Sarach-tongue, “hillside of a great river, place of the swift water” until February 7, 1791 when it became Saratoga County. Because of its favorable position in the angle of the Hudson and Mohawk Rivers, Indian trails crossed it north and south, east and west.
