How do you tell if a rock is an Indian artifact?
If the shape of the item looks like it has been altered for human use, it may be an Indian artifact. Examine the material of the item to compare to known Indian tribes or commonly used materials from the area of the previous inhabitants.
How did Indians make arrowheads?
Native Americans made arrowheads using a chipping process called flint knapping. After the flint was selected, the large piece was cut down to size by a blow to the edge with a piece of hard stone. This is called percussion chipping and was repeated until the piece was thinned and shaped.
What to look for when looking for Indian artifacts?
Walk creeks and look for unnatural colored rocks and shapes. In some cases, natives used non-local stone like obsidian, which makes the points stand out. Flowing water sifts gravel into different sizes along gravel bars. Look for points in gravel bars where rocks are similar in size to the points you’re hoping to find.
