After 25 years of searing Vermont’s northern bogs, the naturalist and writer Bryan Pfeiffer made the discovery of a lifetime. He spotted the shy butterfly that had eluded him and raised questions in his own life about life and death, nature and moving slowly. A former newspaperman who covered everything from fires to health care and politics, Pfeiffer is Vermont’s leading naturalist, spending much of his time searing bogs and fens (there is a difference) for the life that makes our own lives worth living.
