Detailed Description
In this photo, you can see both the fore-reef and main reef area of the complex. The fore-reef slants backwards until it meets the near vertical face of the main fossilized reef. The fore-reef structure is made up of pieces of sponge and coral that were broken off when waves hit the reef millions of years ago.
