The karri tree grows only in South West Australia and is one of the tallest trees in the world. A hardwood tree growing to 90 meters in height, it sheds its grayish bark each fall leaving a pile of shredded bark at its base, revealing smooth new bark in patches of white, yellow, and orange. The trunk extends straight up and has branches only near the top.
Several of these tress have been put into service as fire towers by building platforms near the top made accessible by ladders attached to the trunk. Several trees have also had these ladders intalled to permit access by the public. As there is only one ladder on the trunk, people decending must pass those accending the tree. Not for me.
