Exploring the ancient caves of Andros


This week was windy to say the least. With 30 knot winds gusting in from the East we were forced to move our diving inland to what is locally known as blue hole diving. These incredible cave systems were formed during the ice ages when sea levels dropped considerably. Thousands of years of acidic rain slowly bored in to the limestone substrate creating deep subterranean caves of various shapes and sizes. After the last Ice age, sea levels rose again to fill these spectacular marine dive sites. Here we can observe the blind cave fish, stalactites, stalagmites, flow rock, fossilized coral and a brackish water ecosystem near the surface. Thanks goes out to Graham from Chicago for taking this shot of me inside El Dorado blue hole on South Andros.
