Petrified wood from Arizona, Egyptian granite, and our own Roxbury puddingstone are just some of the rock stars that can be found in this outdoor exhibit, where visitors can take a tour of the world just by strolling through.
Here, you can find a rock that tumbled in an avalanche from the top of Mount Blanc, or a billion-year-old boulder from the bottom of the Grand Canyon.
Get up close and personal with lava from Death Valley, or observe the narrow, black crystals of sillimanite embedded on the surface of gneiss from Mount Washington. Touch a piece of the two-ton chunk of limestone from the Rock of Gibraltar.
