Step into the Past: Hubbell Trading Post National Historic Site, September 2001 Preserved as the oldest operating trading post on the Navajo Nation, Hubbell Trading Post still serves the surrounding Navajo community. Located on the site are the Trading Post, the Hubbell home and a Visitor Center with a demonstration of Navajo rug weaving. For those who are interested, the parks service has a fascinating paper detailing how the Park Service came to acquire and run an Indian trading post. (via Photos from Robby Edwards)
