ROALPS Passport Stamp
Are you a U.S. Lighthouse Society Lighthouse passport holder? ROALPS has a stamp for you! Available in person at Windigo Ranger Station in Isle Royale National Park or by mail, the stamp captures the essence of the Rock of Ages Lighthouse.
If you want your stamp by mail, make sure to include the date you visited, or even better, a picture. Send either, along with a self-addressed stamped envelope and a small donation, to:
Rock of Ages Lighthouse Preservation Society
P.O. Box 3531
Duluth, MN 55803
Please keep in mind that the stamp is not available at the Rock, given that the lighthouse is still closed to the public.
