Dear Heamit,
Thanks for your supportive comments. It is kind of nice to get back to use Google Earth to get back to my deep past. I used to be the first Head of Applications Development Division of the Canada Centre for Remote Sensing (1973-1975). Interpretation and analysis (visual or automated) of satellite and airborne images have always fascinated me, and GE allows me to play with this again. Of course I have done this stuff with ERTS and LANDSat imagery in those days, but now it is accessible to almost everyone!

By the way, the interesting part of this permafrost is that it is at the most southern edge of its occurrance. This is by no means the Arctic, but the Mid Boreal zone. While melting rates have been reasonably consistent in the last 50 years, you could expect significant more change in the next 20 years. Also surprising is that the permafrost occurs in some areas within 50 meters of the shoreline. See image below
