Rocks Redux at the Smithsonian
They’ve been waiting behind closed doors or hidden in rock formations,
but now the big rocks are on display at the Smithsonian’s National Museum
of Natural History. The Janet Annenberg Hooker Hall of Geology, Gems, and
Minerals was just getting started when it opened in late 1997. Here, a
Smithsonian curator and geologist offer a tour of the recently opened Rocks
Gallery, which features specimens as large as a 400-pound lodestone. The
rocks are displayed in ways that tell their stories of plate tectonics
and geologic processes.

John C. Crowell: A Geologist’s Geologist
He forecasted wave conditions for the Normandy Invasion and led
a convoy section across the Burma Road during World War II. Today he
studies and teaches California’s geology. He’s helped us understand causes
of glaciation, the roles of strike-slip faults, and details of Earth’s
past climate. The life of John C. Crowell, professor emeritus at the University
of California at Santa Barbara, has been full of scientific achievements
and contributions taking many forms.
