Walden Pond Map-ALL

The original image beneath the shaded circles, courtesy of the Concord Public Library, is of Thoreau’s engraving of his survey map of Walden Pond.¬†You can explore the soundscape at Walden Pond through this sound map. Just click on the image above to access the map and scroll down the left column to hear the sounds of birds and the trains passing at different points around the pond. Take a moment to listen to how long it takes for birds to resume singing after the train passes.
