Warthin Museum of Geology & Natural History

The original collection of the Warthin Museum of Geology & Natural History was commissioned in 1862 at the request of Matthew Vassar and houses an extensive collection of rocks, minerals, fossils, and other items related to natural history.  For over 150 years, there have been many exciting additions to the original collection, reflecting contemporary interests.  Recent improvements include a permanent exhibit of the museum's beautiful collection of fluorescent minerals, as well as revolving displays of historical materials such as Blaschka glass invertebrates and Brendel paper mache flowers from the 1890's.  The museum serves as a resource not only for Earth Science courses but also for the larger Hudson Valley region.
