Instructions
Familiarize yourself with Native American culture and history in your area. Find where areas tribes lived and try looking near areas of running water or any stone formations. Make sure you have the right to dig on the land for artifacts. If you find an arrowhead in your backyard of your own property then you're legally OK. However, even though it is prohibited to dig on public land, you can propose your reasoning for an archaeological dig to your local government.
Try searching for arrowheads in a river by using a bucket and a sieve. Look for any object that appears to have a circular or fine-trimmed shape. At first, the object may look like a rock, but inspect it closely for any formations that seem unnatural or man-made.
Visit a museum in your area once you've found a Native American artifact. Have a skilled historian identify the artifact and possibly determine its value. Explain where you found the artifact and make sure you know the exact location in case you want to go back to look for more.
