Ten years ago, Anne LaBastille found peace and solitude in the log cabin she built herself at Black Bear Lake. But as the years passed the outside world intruded in various ways: curious fans, after reading her best-selling book "Woodswoman," tracked her down; land developers arrived; there was air and noise pollution and the damages of acid rain. "Beyond Black Bear Lake" is the story of the author"s decision to retreat farther and build a tiny cabin fashioned after Thoreau"s Walden, of her life there with two German shepherds as companions, of the sustaining relationship that developed with a man as independent as herself, and of her renewed bond with nature.
