                                        | Both Ralph Waldo Emerson and Henry David Thoreau visited the mountain and wrote fondly of it. Emerson was a frequent visitor, and made the mountain the subject of "Monadnoc", one of his most famous poems. Thoreau visited the mountain four times between 1844 and 1860 and spent a great deal of time carefully observing and cataloging natural phenomenon. He is regarded as having written one of the first serious naturalist inventories of the mountain. A bog near the summit of Mount Monadnock and a rocky lookout off the Cliff Walk trail are named after him; another lookout is named after Emerson.
