Limestone

Due to its porous limestone geology and small landmass, Bermuda has no natural freshwater sources beyond rainfall. This makes the collection and storage of rainwater via specially designed roofs and cisterns absolutely crucial for daily life.

Discovered by two boys chasing a lost cricket ball in 1907, these natural wonders are formed by limestone dissolution, revealing incredible crystal formations and clear subterranean pools. The caves offer a glimpse into the island's geological past.

Unlike most Caribbean islands formed by volcanic activity, Barbados is a coral island, created by the uplift of coral reefs. This unique geology results in distinctive caves, underground water systems, and a lack of significant surface rivers, shaping its entire landscape.

Due to its porous limestone geology, rainwater quickly drains through the ground rather than forming surface rivers. This unique hydrography means the islands rely heavily on groundwater and desalination for freshwater.

Located on Antigua's eastern coast, this limestone arch was formed over millennia by the relentless pounding of the Atlantic waves. The powerful blowholes and spray make it a breathtaking, albeit sometimes dangerous, natural wonder.
