Geological Map of the United States by the U.S. Geological Survey.  Our beautiful nation takes place above the beautiful rocks of its crust. 

Bronze plaque lists the names of the first 48 states alphabetically and the last two at the base.   Each is associated with a number that is also present on the specimen stone from that state. Alaska is missing a tag. This plaque was covered with lichens and algae before Thorson cleaned with a wire brush.

Stone from Home

Feeling homesick?  Want to see a piece of your home state?  There are two ways:

• You're physically there:  Find the brass plaque in the upper left, which is an alphabetical list of states. Use the list to find a specimen number. Then find that number on a stone on the exhibit wall  (Alaska is missing a tag).  As with reading text, the stones are arranged in lines of stone from top left to lower right.  T Alaska lacks a tag.

• You're there online: Find your state on the drop-down menu or list of links below.

To learn more about the specimen stone from your home state, use either the drop-down menu of list of links.  Each will give you a photograph of your stone in the wall, a close-up photograph, two maps, several links, and descriptions.
