Beetle Kill (BK)logs were used in this Colorado Tree House project. Half round BK small logs were stained and used for the outside of the "Fort." Large center log is 18 inches in diameter, 11 feet long and weighs 508 lbs. This log is mortised all the way through to accomodate the 6"x7" beam held in place by hardwood pegs. The lower level has split log flooring and area for a sand box. A mortise and tenon joint was used to anchor the side beams into the 10x10 end posts.
