Found today by the Kennebec river near a known indian site. I'm new to the native artifacts but this caught My eye. Any help appreciated. Thanks

From what I can make out from your pictures I would say no, it's not an artifact. I don't see any evidence of it being altered by man that I can see.

tiny rock isnt it? Its natural but for the future try getting a pic of the end that looks to be sharp to you.
