Melting Mendenhall Glacier Reveals Ancient Forest An ancient forest has thawed from under a melting glacier in Alaska and is now exposed to the world for the first time in more than 1,000 years. Stumps and logs have been popping out from under southern Alaskas Mendenhall Glacier — a 36.8-square-mile (95.3 square kilometers) river of ice flowing into a lake near Juneau — for nearly the past 50 years. However, just within the past year or so, researchers based at the University of Alaska Southeast in Juneau have noticed considerably more trees popping up, many in their original upright position and some still bearing roots and even a bit of bark, the Juneau Empire first reported last week. There are a lot of them, and being in a growth position is exciting because we can see the outermost part of the tree and count back to see how old the tree was, Cathy Connor, a geology professor at the University of Alaska Southeast who was involved in the investigation, told LiveSciences OurAmazingPlanet. Mostly, people find chunks of wood helter-skelter, but to see these intact upright is kind of cool. huffingtonpost/2013/09/23/mendenhall-glacier_n_3975699.html
