I got interested in Indian artifacts as a kid. I turned over all I found to a buddy that had a large family collection , mostly picked from the shore of the Monongehela River 5 miles from my home in eastern Greene Co. , Pa.. What fired me up , was the Indian burial ground , near my Grand Parents home. The local College dug up , and left the holes open , and easy to find. As kids , my buddy and I used to go there and look at the holes. Never bothered anything , 'cause it just didn't feel right to disturb any grave site. Several years later , a local farmer plowed the field on the hill top , next to the woods where the grave sites were. Wow , a village site appeared. The Indians must have eaten a ton of Mon. River mussels. The site was about 50 yds. diameter in size , due to the ground being covered with broken mussel shells. Once the clams were eaten, the shells were not wasted , but used to keep folks out of the mud during wet weather. I gave my friend a fire stone , a skinning stone , and many arrow heads. There were no houses near the site , and I'll bet it is still the same as it was back in the mid 1950's.......oldwood
