Cascade point

The Cascade point, often called Cascade leaf point, is a type of stone projectile point that is associated with the Old Cordilleran culture, which persisted between about 9000 BC and 5500 BC in the Pacific Northwest of what is now the United States. Cascade points are leaf-shaped, with points at both ends, and were made from chert (or sometimes basalt) through a process of pressure flaking. They were attached to spears for use in hunting large land mammals.
