Logstown was a historic Indian village located a short distance northwest of this spot. It was founded by Shawnees and later occupied also by Delawares, Senecas, Mohawks, and Wyandots. In 1748 Conrad Weiser, agent of Pennsylvania, negotiated a treaty there with the Indians that opened the region west of the Allegheny Mountains to Anglo-Saxon influence and development. On June 11, 1752, the Treaty of Logstown was made there between the Iroquois Indians and the Virginians, giving the latter the right to build a fort and establish a trading post at the forks of the Ohio (Pittsburgh). Major George Washington held councils at Logstown with Tanacharison, Scarouaday, Shingas, and other Indian chiefs from November 24 to 30, 1753, while on his important mission to Fort LeBoeuf.
