Wonders of Geology: Giant's Causeway of Northern Ireland

Giant’s Causeway with its unusual formations attracts thousands of visitors each year to Northern Ireland. Some geologists claim that the Causeway was formed over 60 million years ago by intermittent periods of volcanic activity. But other geologists, who approach Giant’s Causeway with a biblical understanding of the past, state that this wonder was formed around 4,500 years ago as a result of a single, great catastrophe.
