Resting on the site of another Native American archaeology site, Nevada's Lost City Museum covers a lot of historical ground throughout its displays, but maybe none more important than the cultural artifacts that would have otherwise been destroyed as Lake Mead was created.
Originally opened as the Boulder Dam Park Museum in 1935, it was built to house the finds being unearthed at the Pueblo Grande de Nevada site, which was rich in Anasazi history and artifacts. As Lake Mead filled with the water held back by the newly created Hoover Dam, it began to submerge important archaeological sites. It's hard to say exactly how much was lost beneath the waters of the man-made lake, but the museum saved what it could.
Possibly the most iconic feature of the museum is the replica Anasazi pueblo cluster which is built directly on the foundation of an excavated archaeological site.
Currently owned and maintained by the State of Nevada as one of its seven state museums. The small but extensive collection focuses on the history of the region as far back as 8000 BCE, though most specifically on the Pueblo Grande de Nevada site. The artifacts paint a vivid picture of a culture that in some part was literally drowned out by history.
