TnMountains has it right..Look for the flaked chips and they will lead to the arrowheads and other artifacts. Here in Vermont the best way to tell if your in a good spot is to find quartz flakes that are usually( first pic. )blue gray, gray, white. They also used (second pic) a dark black chert ( Mt. Independence is where they obtained alot of this ) and it was another favorite material they used. Find these flakes and you will find artifacts. I looked for arrowheads in my teen years while fishing and never found one. I was in the right spot but didn't know what to look for. When I was shown what to look for I found a arrowhead the first time out. My favorite hunting grounds are plowed cornfield next to rivers , lakes , ponds, streams, brooks. Then it would be sandy lake shores , and creek banks and bottoms. Here is a pic of some books I started out with that help me locate a few spots. I see you post about Arlington and Bennington...I have never look south but I was told that Bennington is loaded with artifacts and the river that runs along rt.313 out of Arlington heading to cambridge has artifacts long it. Heres some more pics of artifacts, peices and parts all from VT. I will post pics of my good finds that are in my safe at a later time. They are out there waiting to be found and somedays you will get skunked. Don't give up.....Cornfields + Water = Artifacts.
