Image Galleries
Five decades of geological documentation. Tunnel faces and excavation geology from New York City's water and transit projects, a mineral collection assembled across four continents, and thin sections of rock from the Moon.
Most of these photographs were taken underground, in working tunnels, in the days between excavation and lining — conditions that no longer exist and cannot be revisited.
Astrogeology
Thin sections of Apollo lunar samples, photographed through a petrographic microscope.
Field & Tunnel Geology
Rock as it was encountered — mapped during construction of the Queens Tunnel, the Brooklyn water tunnels and other municipal excavations, and studied afterwards in thin section.
