Here's Al standing pretty close to what is a very sudden, and extreme drop off. It's hard to tell in the picture, but we are very high up above those rocks and the ocean. All the rock that you see, surrounds Green Island. The island was formed by volcanic eruptions so there is large amounts of volcanic rock all around. This helps the water to be super clear which makes it a great spot for snorkelling and diving. (which we did on Sunday)
