Last weekend we got to visit the state champion Camperdown Elm in Port Gamble. It's only 26' tall but take a look at the trunk that's under that canopy - it's quite impressive. This tree is extremely unique in that it relies on humankind to keep it alive as a species. As the sign in the photo says, the tree must be grafted to a Scotch Elm tree to get started as it is a mutant and cannot self produce.
