Editor's Note: Today's story is the answer to the August Puzzler.
Tides are among the clearest signs of the Moon’s pull on Earth. Just 239,000 miles (385,000 kilometers) away, the Moon's gravity pulls on Earth’s oceans and solid crust, subtly distorting them into a more oblong shape with bulges roughly extending toward and away from the Moon.
High tides happen throughout Earth's oceans, but in some places they leave an unusually strong fingerprint on the landscape. Among those places is Roebuck Bay, a crescent-shaped feature in the Kimberley region of Western Australia.
