300,000 years ago, a meteorite hit western Australia, boring a hole 400 feet deep and 2,880 feet across into the surface of the earth. This crater, now known as Wolfe Creek Crater, gradually filled with sand. But it’s still 200 feet deep and the second largest meteorite crater in the world.

Water collects in the basin of the crater, so the center of this hole in the desert is filled with green plants. You can see more photos of the interior here.

Although aboriginal peoples of Australia knew about the crater for a long time, the Western world confirmed its existence in only 1947. It quickly captured the popular imagination and served as the setting for a popular murder mystery novel.
