Nature has the extraordinary ability to craft incredible shapes over time. This is the case off Central America, where we have the Great Blue Hole, a cavity formed by erosion. We present this magnificent geological formation.
The Great Blue Hole is a chasm formed by erosion of soluble rock, here limestone, filled with water. Located off the coast of Belize, in Central America, the geological formation is part of a group of small low-lying islands, made of sand and coral, and called the Belize Barrier Reef.
Renowned for its incredible beauty, the Great Blue Hole was made famous by Jacques Cousteau, renowned oceanographic explorer who stated it as one of the ten most beautiful diving sites in the world.
The place was formed during the last ice age, when sea levels were much lower than today. The “hole” was when a limestone cave, but rising water flooded the cavity, causing the roof to collapse.
