The Gambell Sites are five archeological sites which established a chronology of over 2000 years of human habitation on St. Lawrence Island near Gambell, Alaska. The sites (named Hillside, Mayughaaq, Ayveghyaget, Old Gambell, and Seklowaghyag) have provided evidence of four cultural phases of the Thule tradition. Digging first began in 1927 and the sites were labelled a National Historic Landmark in 1962. As with all previously existing National Historic Landmark sites, the sites were listed on the National Register of Historic Places when the registry opened in 1966.
