I'm trying to upload some pictures of some wood i scrounged for a few months ago. It is very dense like nothing i've seen before. It was easy to split with a log splitter and all of the bark came off right away as i split it. It also has a distinctive smell to it when you hold a split up to your nose. After reading about black locust on this site i was thinking that it could be that but it didn't have any thorns on the bark. The woman who i got it from did say that it had been down for a year. It's very dark in color on the ends. I'm not sure if the photos will work but i will try.
