I just thought some of the fans of Baxter would be interested in seeing that this map shows two major proposed trails (in orange). One is a link between the Wassataquoik Lake Trail/Nesowadnehunk Area and Northwest Basin Trail/Davis Pond Area. One is a link between Grand Falls/Russell Pond Area and Twin Ponds/Katahdin Lake Area on the North Side of North Turner Mountain. These could potentially open up new types of backpacking loop options, but I wouldn't hold your breathe because I could not find any additional information on actual proposals and/or timetables. Also it is interesting to see how the central core of the park they intend to let burn, to an extent, if a natural fire starts (similar to how National Parks approach natural fires).
