I have crossed this tree a couple of times in the last two weeks. It is between the BP sign and the end of the long BP switchback. Someone has cut all of the branches off and left only stubs. The tree is large, over 2 feet in diameter, and there is not an easy way to cross on either side. It does not cross the trail at a 90 degree angle but lies parallel to the trail blocking the trail for considerable distance. It is an acrobatic task to traverse that area and not without risk of injury. It will be a choke point during the race and the subject of many complaints if not removed.
