Earth and Environmental Sciences
Higgins Professor

At the bottom corner of the engineering school's Seeley W. Mudd Building, punctuating polished slabs of pinkish-red granite, chunks of pale blue quartz reflect changes deep in the Earth dating back 600 million years. Part 3 of the Columbia Geology Tour, following along with Professor David Walker as he talks about the stones that make up Columbia University buildings, and what they can tell us about Earth's past.
