    The NPS Passport Cancellation Stamp is a voluntary program that nearly all parks within the NPS participate. Visitors can purchase their official NPS Passport 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 park and the date it was visited.

    Through a network of sites, programs and events, Silos & Smokestacks National Heritage Area tells the story of farm life and agribusiness—past and present. Visitors can learn about and experience agriculture at a variety of museums, historic sites, and farms. 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. For more information, visit
