The Great Blue Hole is a large submarine sinkhole off the coast of Belize. It lies near the center of Lighthouse Reef, a small atoll 70 km (43 mi) from the mainland and Belize City. The hole is circular in shape, over 300 m (984 ft) across and 124 m (407 ft) deep.[1] It was formed during several episodes of Quaternary glaciation when sea levels were much lower - the analysis of stalactites found in Great Blue Hole shows that formation took place 153,000, 66,000, 60,000, and 15,000 years ago.[2] As the ocean began to rise again, the caves were flooded.[3] The Great Blue Hole is a part of the larger Belize Barrier Reef Reserve System, a World Heritage Site of the United Nations Educational, Scientific and Cultural Organization (UNESCO).[4]](http://25.media.tumblr.com/tumblr_m3zpjkVllC1r8x2ybo1_250.jpg)

A boy left his bike chained to a tree when he went away to war in 1914. He never returned, leaving the tree no choice but to grow around the bike.
