No finish, just came off the planer. Surface was a dark grey weathered look before planing. Will try to cut the end off one and get a picture of the end grain later. Planed from 1" to 3/4"+.It doesn't look like Pine. It doesn't look like it was planed very deep. It appears that there is some finish on the board.
Pennsylvania is (was) pretty well blessed with a plethora of different wood, including cypress, ash, oak, walnut, cherry, and until the blight hit, chestnut and elm. Forestry dept says 162 native species.either one of those is probably more likely than cypress. Which trees are more prevalent in the area you found them?
