Today’s Three Weeks Behind the Scenes photograph takes you into the Academy’s mineral vault. Collected at sites in England (above center) and Chile, these copper specimens are from the Academy’s W.S. Vaux Collection of minerals. These specimens show native copper in its dendritic (branching) form. The Academy’s Mineral Collection also has beautiful native copper specimens from the Keweenaw Peninsula in Michigan, one of the mineral’s best-known localities in the world.

Visit the museum in April and add a mineral to your very own collection box. Learn more about the rockier side of the Academy’s history.
