Ralph Waldo Emerson writes in his journal:
Yesterday a ride and a walk with Thoreau to Acton. We climbed to the top of Nagog Hill, and afterward of Nashobah, the old domain of Tahatawan and his praying Indians. The wide landscape is one vast forest skirted by villages in the horizon. We saw Littleton, Acton, Concord, Chelmsford, Tyngsboro, Dracut. On the western side, the old mountains ending with Uncanoonuc on the north. The geology is unlike ours, and the granite ledges are perpendicular. Fort Pond is a picturesque sheet with a fine peninsula scattered, park-like, with noble pines on the western side; Grass Pond a pretty lake; Nagog seen from Nagog Hill is best, and Long Pond we came to the shore of. These four ponds dictated, of course, Tahatawan’s location of his six hundred acres. Also we visited the top of Strawberry Hill, and a big chestnut tree.
