I have been cutting alot of wood for my family, and to get to some of the good stuff I have been having to cut alot of other stuff. The wood in question has a gatorback looking bark that is greyish. The wood inside has a very tight grain and is a very light yellow with darker yellow rings. The trees grew almost straight up with the first branches about 2/3 to the top. The trunks are between 14" and 18" and the height is around 30'. Sorry, I have no camera to take pics with. i want to have some ideas on what these are and how they will burn. We have burned some and they seem slow, but they are fresh cut.
