Zane- Thanks for the offer to help, but I am about 90 miles northeast of Bangor Me. , way up there from you.
There are tons of sites like that up here, as well as stone and rock foundations and celler holes, not easy digging most of them but with a little perceverance you will find one once in awhile that hasn't been touched and will spit out some nice finds. Dam snow has got to go!
