Toad-ally in love!

The Wyoming Toad was once a critically endangered species-at one point, there were only seven toads in the wild. Since 2008, the River Museum has helped breed and release 50,000 Wyoming toad tadpoles back to Wyoming.

How many objects are in our collection?

The Dubuque County Historical Society has 26,000 artifacts, but that number changes often through new donations and deaccessions.
