I know a thing or two about the area....how about some pictures of the other side...what kind of stone is it?....is that how it looks or is it covered in dirt?
This “Cascade Point” was found in McCoy Creek near the eastern edge of the Alderleaf property in July 2010. It is likely from the Olcott Complex, a grouping of stone artifacts found in the Snohomish, Snoqualmie, and Skykomish drainages that date from 4,500 to 9,000 years ago! It is made from basalt, which is a type of igneous rock found here in western Washington. The size of the piece indicates that it was possibly used as an atlatl dart tip.
