Don, >> The problem is going to be separating rising due to "hot spot" thermal pluming from glacial rebound, that's known from Holocene marine fossils in the Champlain Valley to be 150 meters or more and is probably still happening. << I think they're well aware of that. They're specifically looking not only for vertical uplift but also for horizontal spreading. They hope to find a doming pattern to the motion, which would indicate a thermal plume from below rather than postglacial rebounding. Jon W.
