Manzanita Lake Naturalist's Services Historic District, Lassen Volcanic National Park

The Manzanita Lake Naturalist's Services Historic District encompasses the historic area devoted to visitor interpretation services at the northwest entrance of Lassen Volcanic National Park in northeastern California. The district's earliest structures were built by Benjamin and Estella Loomis, who were instrumental in the establishment of the park and among the park's first concessioners. The 1927 Loomis Museum and its seismograph hut were built by the Loomises and were donated, together with 40 acres of land to the National Park Service in 1929. The Loomis House, also known as the Loomis Art House and Manzanita Lake Ranger Station, was built about the same time as the museum and served as their residence, photography studio and shop until the 1950s under the name "B.F. Loomis Photo and Art Store". ()
