Rim diameter: 32 kilometers (20 miles), Age 290 +- 20 million years
These twin circular lakes were formed simultaneously by the impact of an asteroidal pair which slammed into the planet approximately 290 million years ago. The larger western lake contains a ring of islands with a diameter of about 10 kilometers that surrounds the center of the impact zone. They constitute a central uplifted area and are covered with impact melts.
