Hey Pete,
Welcome to our little neck of the woods. Its warm and welcoming here most of the time....lol
Getting started isn't too hard at all. Ask, look and listen. Ask people about relics, normally there are people around you close that have the fever and many are willing to share knowledge. If you have a local library, go in and ask them if anyone around is an Indian relic nut....normally they have a good grasp of patrons and can steer you in the right direction.
Apart from that, you need to find areas of turned earth...plowed fields, pipelines, roads, timberlands that have been cleared and planted etc.....anywhere there is raw earth that can be checked out. Things to look for in geology is high ground preferably overlooking a creek, river or body of water. Also large springs drew Indians. The main thing is water, always look for a close water source.
Things to look for regarding site location. Look for chips of flint, small fingernail sized and larger pieces of worked rock, like slivers of broken glass, also small pieces of pottery and of course broken points and larger worked (chipped) tools. If you find this material it is most likely you are on a site of some type...village, camp or other.
Always have permission to surface hunt before you go onto property. It will save you heartache later and insure goodwill with land owners.
Happy Hunting,
Atlantis
