Landscapes shape our sense of place, yet Earth is constantly changing. The forces of volcanism, wind, water, sun, and, yes, people, relentlessly conspire to transform what we consider familiar terrain—pummelling cliffs into beaches, eroding vast canyons, forming new land with bubbling lava, and shifting the course of mighty rivers. In the last 50 years alone, hundreds of natural landmarks around the world have drastically shape-shifted—or worse, disappeared.
Sites like these serve as reminders that our planet is a dynamic place. Here are landmarks the world has lost—and some fragile sites you can still visit.
