The main museum building was built 1928-29 by H. Arden Edwards, with additions in 1930.","why_significant":"The nomination argues the Swiss-chalet-style museum, built into and around natural granite boulders, blends natural setting and hand-crafted construction. It also survives as a 1920s-30s private roadside museum. The site is tied to Edwards' Native American pageants of 1932-1935, to later owner Grace Wilcox Oliver's expansion and school tours, and to use as a film and art location.","narrative":"Perched at the southern base of Piute Butte in the high desert of the Antelope Valley, this museum complex was built by artist and teacher H. Arden Edwards beginning in 1928 to house his collection of Native American artifacts. The wood-framed, stucco-covered building is wrapped around natural granite boulders that form walls, steps, a fireplace and even floors, and its steep roofs, towers and bargeboards give it a Swiss chalet look. Edwards also staged four annual pageants on local Native American life between 1932 and 1935 in a rock amphitheater nearby. Anthropologist Grace Wilcox Oliver bought the museum in 1939, added her own collection, started school tours and built cottages and other visitor buildings in the 1940s. Art students, filmmakers and television crews have also used the grounds. The main building is the only contributing resource; the later cottages are counted as non-contributing. The property is now part of the California State Park System.","period_of_significance":"1928-1935","architect_builder":"H.
