During [Edgar Allen] Poe's years in Philadelphia, 1839-1844, he often visited the Wissahickon. He advises those who would see the best of the creek to go out the Ridge Road to Roxborough, and, "taking the second lane beyond the sixth milestone, to follow this lane to its terminus." This route would bring him down to the creek almost opposite the Monastery. It was just below here, on Mom Rinker's rock, he saw the elk, that he wrote about in "Morning on the Wissahiccon," in The Opal for 1844.
