Picked this up along the river. Translucent, seems worked and polished in some areas. Any ideas?
I remember you writing once you were near Maine.
There are a couple of sources in NB that can look like that. If you are on the Quebec side I’m not sure.
One is off a beach in St John where European flint ballast stones were dumped, and quite often quarry debris included debitage. The main local material is Washademoak chert, you can google pictures of it and compare it in natural light or when it isn’t backlit. Another is a small quarry inland on the St John river. It produces reddish to tan chert as I understand it, but it isn’t common (it might be related to the Washademoak chert.)
