Had a client call with an emergency take-down late last week. He had a 28" diameter 60' red maple in his backyard that had a spiralling split in it. I stopped over to check it out (even though I ain't done with my living room project quite yet) and see what the story was with the tree. Well, upon looking at it, it had a PILE of problems. I determined that the tree was struck by lightning many years ago (if you've ever seen a lightning struck tree, alot of times they get a spiralling wound down the entirety of the trunk right into the ground). This tree had that, and it was totally hollowed out to boot! This led the tree to twist and flex over the years, and that healed-over spiral wound eventually split open, and led to one of the most unstable trees I ever dropped...... Ended up dropping two red maples, still have two more big ones to do for him in a week or so. I'll end up with around 3 cord or so of red maple from this job. Feels good to get back at it!!
