Where can I buy authentic indian arrowheads in Denver area of Colorado? -

Take the drive down to Pueblo on I-25.The plains around there are abundant in genuine arrow heads, to the extent there is no room for the fakes in the shops in Pueblo. Either head out to the plains (with permission of the land owner) and find your own, or visit the many smaller stores to find them for sale. Try also the antique shops in the smaller towns along the way.Tip: avoid tourist areas if you want the genuine article.

Check with some antique shops. Sometimes they have framed arrowhead collections. Also a rock collecting shop might have some non-reproductions.
