A hexagonal basalt pillar carved by cooling lava/Geology & Minerals
The Giant's Causeway in Northern Ireland consists of roughly 40,000 interlocking basalt columns formed by an ancient volcanic eruption about 60 million years ago. Most columns are hexagonal, though some have four, five, seven, or eight sides. A typical column is about 30 to 40 cm across and up to 12 meters tall. The remarkably regular geometry results from the slow, even cooling and contraction of thick lava flows. Legend attributes the causeway to the giant Finn McCool.
