Clark County Museum in Henderson, Nevada, preserves the cultural, social, and industrial history of Southern Nevada on a 30-acre campus with exhibit halls, historic buildings, and outdoor interpretive spaces. It grew from the collection of Anna Roberts Parks, whose daughter and historian Maryellen Vallier Sadovich helped secure a permanent home after Parks died in 1962. Opened in 1968 as the Southern Nevada Museum, it later moved to a larger site, added the Boulder City depot, and eventually came under Clark County management. Its exhibits trace regional history from Native American cultures through mining, railroads, Hoover Dam, Henderson industry, and Las Vegas gaming.
