The National Mississippi River Museum & Aquarium and Mathias Ham Historic Site, both Partner Sites within the Silos & Smokestacks National Heritage Area (SSNHA), are proud to announce they have been selected as a National Park Service (NPS) Passport Cancellation Stamp location.
Beginning this month, both facilities will be placing a NPS Passport Cancellation Stamp at their location. A total of twenty-one SSNHA Partner Sites will have NPS Passport Cancellation Stamps available. A few of the local sites include:
Hurtsville Interpretive Center, Maquoketa
Mines of Spain Recreation Area, Dubuque
National Farm Toy Museum, Dyersville
The Sawmill Museum, Clinton
The NPS Cancellation Stamps will be located inside the entrance at the Museum & Aquarium’s Mississippi River Center and in the entrance gift shop at the Mathias Ham Historic Site.
The NPS Passport Cancellation Stamp is a voluntary program that nearly all parks within the NPS participate. Visitors can purchase their official NPS Passport through an NPS Park or through eParks.com and start recording their visit to a NPS site by stamping their passport with a rubber cancellation stamp. The cancellations, similar to those received in an international passport, record the name of the site and the date it was visited.
One of 49 federally designated heritage areas in the nation, Silos & Smokestacks is an Affiliated Area of the National Park Service. The heritage area covers 37 counties in the northeast quadrant of Iowa. To learn more about Silos & Smokestacks National Heritage Area, please visit SilosAndSmokestacks.org.
