This week, a group of geologists report that they've found a lost continent off the coast of Scotland. 55 million years ago, about 10 million years after dinosaurs died out, a chunk of the seafloor erupted from beneath the water. It created a small continent that existed for at least a million years, covered in dramatic mountains and valleys, and irrigated with streaming rivers.
Eventually the landscape sank back beneath the waves, its once-sunny mountains buried beneath 2 kilometers of seabed. How did this happen? The answer reveals that our planet is even more dangerous and magnificent than we knew.
