Instructions
Research some locations of Native American tribe sites. Arrowheads were introduced by Native Americans at least 9,000 years ago. Many ancient sites can be found in North and South America.
Narrow down the search by looking for high plateaus or level ground near a stream, where hunting could have possibly happened during this time. Most hunting and temporary hunting camps would be near water. Get permission to scope out these areas.
Wait for a sunny day after it's rained. The rain may wash away surface sediment and make it easier to find exposed arrowheads. Walk over the ground when it's sunny out and scan the ground for protruding objects.
Look for broken ground where fresh dirt is already upturned. Check freshly graded earth around road construction sites and other building operations.
Look along river and stream beds. Sometimes arrowheads turn up on the banks of rivers or lakes since arrowheads can get carried by water currents.
Look for pointy edges puckering from the ground. Look over clay banks along streams, since the water might have cut into a layer of buried artifacts. It's less likely to find anything under the clay since it's such a thick layer of earth.
Target your search on small areas. Take out your sieve and sift through the sand. Scoop up an area of earth that shows signs of debris. Shake the soil in your sieve to separate the irregular-shaped rocks from the possible arrowheads.
