Old Kasaan was completely abandoned by 1904, and the remains were partly destroyed by fire in 1915. The site was declared a national monument in 1916, though Old Kasaan National Monument was largely neglected and a planned restoration was not done. In 1938 five historic and three replica totem poles were moved to New Kasaan. In 1955, the site was removed from the National Park System. It became Forest Service jurisdiction, which established a 38-acre Old Kasaan Village Historical Area in 1957. The relocated totem poles and a relocated house in New Kasaan were designated the Chief Son-I-Hat's Whale House and Totems Historic District in 2002.
