• Bloodsuckers, bogs and bugs: Welcome to Mud Pond Carry After a wet and lengthy portage in the summer of 1857, Thoreau proclaimed 'We were rejoiced to see ... dry things in that part of the world.
• Tram, train remnants of logging's glory days Thoreau anticipated the sort of large-scale lumbering that the tramway and locomotives eventually made possible in the Maine woods.
  
• 'I wished ... to see a moose' While not a sportsman, Thoreau wanted to observe a hunt for the 'great frightened rabbits.'

5 - Umbazooksus Stream - A narrow, slow-moving stream that meanders through a meadow of sedge and wool-grass. The woods are far back from the shore here, prompting Thoreau to shout out several times "to awake an echo." Joe Polis, the author's American Indian guide, politely reminded Thoreau that they were looking for moose, and his shouts would scare the animal away.

6 - Lock Dam - This dam between Chamberlain and Eagle lakes was built in 1841 to raise the level of Chamberlain Lake and reverse its flow from north to south (enabling logs to be sent to Bangor rather than Canada). Thoreau's party had trouble finding the dam, writing "There is no triumphal arch over the modest inlet or outlet, but . . . it trickles in or out through the uninterrupted forest, as through a sponge."

7 - Chamberlain Farm - This was a working farm and lumbering depot in Thoreau's time. The author, returning from Eagle Lake in 1857, camped on nearby Hog Point and walked to the farm to get four pounds of brown sugar. Today, the farm largely is overgrown with raspberries, purple vetch and dogwood. One of the original buildings - probably a bunkhouse - still stands.

8 - Eagle Lake - Thoreau stopped here on July 28, 1857, on the southeast end of Pillsbury Island. It is the northernmost point in Maine that Thoreau visited. He and his companions ate dinner and waited for a thunderstorm to pass before returning to Chamberlain Lake. Today, the campsite on the island is named for Thoreau, and an eight-point buck who lives here will greet you, and even eat out of your hand. A stand of old-growth white pine can be seen directly across the lake from the campsite.
