You can spend a lifetime exploring the Great Barrier Reef and still not see all of this colorful coral realm - it’s nearly the size of Montana. Sprawling off the east coast of Queensland, Australia, the Great Barrier Reef is not a single reef but a group of more than 2,800 distinct entities. It stretches over 1,250 miles (2,000 kilometers) north to south and covers some 135,000 square miles (350,000 square kilometers) in total.
Thoroughly enjoyed this challenging puzzle.
Central color to get you started with ocean and sky portions making this one more difficult to finish. Nice photo!
