Geologists call them raised beach terraces - ancient coral reefs lifted into the air by tectonic collision, preserved one above the other like the rings of a fossilized tree. On the Huon Peninsula of Papua New Guinea, these steps march upward from the beach to elevations of nearly 500 meters, the clearest record of ocean level changes over the last 125,000 years found anywhere on Earth. UNESCO has nominated them as a candidate World Heritage site - a stairway to the past, as the application calls it. The peninsula itself is still rising, about a centimeter a year, as the Pacific plate slides under the Australian plate and buckles the coast upward.
