the project unfurls as a series of collaborations centered at twelve distinct sites—an impact crater, a nuclear testing ground, a primeval forest, a nearly submerged island, an open pit mine, and more—that together build a portrait of Earth, its converging timescales, and its interconnections. Improbably, these 12 sites are located along a single geographical ring: one unifying “great circle” stretching 25,000 miles around the planet.
An interesting project and an engaging website.
