They are probably atlatl dart points, but some are large enough to have been spear points. They derive their name from the specimens throughout the Susquehanna River Valley in the northeastern United States, particularly Pennsylvania and New York. == Description ==
Susquehanna broad points sizes generally range from 1 1/2 inches in length to 4 inches with an average of about 1 1/4 inches in length. The blade is triangular, the base is narrower than the ears.
