Bare Island points(called Merrimack points in New England), are narrow points with a triangular blade. Shoulders are usually well defined with parallel sides. The base can be straight or slightly convex, never concave. In New England, these points are regarded as the last of the Neville Complex points(Neville-Neville Variant-Stark-Merrimack) and they appeared near the end of the Middle Archaic Period, or about 6,000 years ago, and extending into the Late Archaic.
