The Leventhal Map Center is exhibiting Beneath Our Feet: Mapping the World Below, featuring 400 years of subterranean maps from their collections. These visualize volcanos, catacombs, pipelines, mines, and seabeds, ranging from 19th-century geological surveys to 21st-century sensing technology. The show follows a BPL exhibition on mapping weather and climate that similarly considered the evolution of the earth sciences through topographical art.
