As we walked through the grounds of Chateau Ste. Michelle after the Avants car event, we came across this tree.  As we looked at it we concluded that it was a single tree that was coming out of the ground in various places.  However, we are not arborists so could be completely wrong.  It just looks like it springs from a single source under ground and breaks the surface in various places.  If you know about trees and more specifically this tree, let me know.
