I always enjoyed hunting for arrowheads, spear points, and other native tools with my dad when I was a kid. Now that I am older (grown?!) I still can't help but sift through the fresh gravel beds by the creek after a flood. I've have only ever found these two points. The first was found in the Wissahickon Creek outside of Philadelphia. I estimate that this one is several thousand years old. The second was found in the dirt around a fire pit at a YMCA camp in Jackson MI. I think this one is about 1,500 years old. Of course these dates are only speculation and I am eager to have them either corrected or confirmed! Thanks for looking!
