I live in Connecticut and still cleaning up from a tornado that hit here last year . I cut up a tree today that was extremely soft. Chain saw went through very easily. It has a green color in the core and the wood is physically very light . Wondering what this is and should I even bother using it for firewood as it is very light and probably has low BTU. There is a second picture of another three where the wood seems more dense, and a smooth bark. Curious about people's opinions on should I burn this, especially the very light wood.
