Walden Pond Reservation is located about 10 miles North-West of Boston, Massachusetts.
The reservation is 335 acres (136 ha) in size, and the main feature is Walden Pond, a 64.5-acre (26.1 ha) body of water.
A short way north of the pond the site of Thoreau's cabin is marked by a series of granite posts. Portions of the pond's shore are beach,
while other parts descend steeply to the water from trails that ring the pond.
The writer and philosopher Henry David Thoreau lived on the northern shore of the pond for two years starting in the summer of 1845. His account of the experience was recorded in Walden; or, Life in the Woods, and made the pond famous. The land at that end was owned by Thoreau's friend and mentor, Ralph Waldo Emerson, who let Thoreau use it for his experiment. Thoreau is credited with encouraging a respect for nature at an environmentally degraded site.
Boston's "Ice King," Frederic Tudor, harvested ice yearly on Walden Pond for export to the Caribbean, Europe, and India.
In his journal, Thoreau philosophized upon the wintry sight of Tudor's ice harvesters: "The sweltering inhabitants of Charleston and New Orleans, of Madras and Bombay and Calcutta, drink at my well ... The pure Walden water is mingled with the sacred water of the Ganges."
