Long story short. Had a box elder that was almost all dead. Dropped it just before start of covid. Cut up stump had some great wood. Rest tree sat on patio for almost 3 years. Finally got around to cutting some up but wood very dark amd flame less pronounced plus looks like ants got into it. Is this to far gone to save? Middle still very solid however a large crack in a rough circle all through middle of log. Sawed off bottom 2 feet today and cutting through it some log fell apart from crack area. Appears almost like 2 tree trucks grew together as there a very dark section in middle of tree too. Here a few pics. Thinking best to go to burn pile instead of paying saw mill guy to mill it up. Please give me your thoughts.
