Over a period of three years, Thoreau made three trips to the largely unexplored woods of Maine. He climbed mountains, paddled a canoe by moonlight, and dined on cedar beer, hemlock tea and moose lips. Taking notes constantly, Thoreau was just as likely to turn his observant eye to the habits and languages of the Abnaki Indians or the arduous life of the logger as he was to the workings of nature. He acutely observed the rivers, lakes, mountains, wolves, moose, and stars in the dark sky. He also told of nights sitting by the campfire, and of meeting men who communicated with each other by writing on the trunks of trees. In The Maine Woods, Thoreau captured a wilder side of America and revealed his own adventurous spirit.
