I am a bit of a history buff so this museum sounds like it would be pretty cool to check out. Its called the Lost City Museum.

This "Lost City" is known as Pueblo Grande de Nevada. It is part of the Anasazi Indian ruins located along the Muddy and Virgin Rivers valleys. The area is thirty miles long.
This site was excavated and a lot of things were discovered. They have found stone tools, ancient salt mines, pueblos, jars and jugs, rock art and so much more.

This place is really amazing from what I have read. The items that are on display are ancient. It is wonderful that they have been able to preserve this piece of history.
