Columbia Geology Tour Part I


Earth and Environmental Sciences
Higgins Professor

Tucked away in back of Columbia University's iconic Low Library building sits the Burden Room, a hushed, wood-paneled monument to the Gilded Age. Hidden there lies the evidence that 400 million years ago in the Devonian, the moon was a closer neighbor, and the Earth took just 21 hours to spin through a day. Join Professor David Walker on the Columbia Geology Tour, a look at the university's buildings and what stories their stones can tell about the past. First of 7 parts.
