Bud Wobus, professor emeritus of geology at Williams College, leads a geology presentation and walk around the Clark’s campus. Wobus guides visitors through the history of the granite slabs that comprise the Manton Research Center and Tadao Ando-designed Clark Center. Discover how the minerals and patterns—art forms in themselves—can be interpreted to trace the granites of the grounds beyond the Manton Research Center’s fiftieth anniversary.

Free. Advance registration required. Capacity is limited. Meet in the Manton Research Center reading room.
