Wow. Contest #30 was really a stumper. All-time low for correct answers. A whopping two people got this one right. The correct answer is the Lonar Crater in India. It was created abotu 55,000 years ago and is partially filled with salt water. It is the only salt water crater lake in the world and one of the only craters made in basalt. Because of this (the basalt part) some scientists think it might be the best example on Earth of the type of craters found on Mars.
Skip from Austin and Karel get gold stars this week and a letter from the teacher to put on the fridge.
