Unusual rock formations like the Devil's Postpile in California and the Giant's Causeway in Northern Ireland have drawn curious visitors for generations. For the first time, scientists have been able to recreate the process that led to the strange beauty of these geometric rock columns.
The Giant's Causeway is comprised of around 40,000 interlocking basalt columns that resemble a footpath. Irish mythology holds that it was part of a bridge between Ireland and Scotland created so giants could fight. While there are no specific stories about the Devil's Postpile, the name implies a supernatural feeling around the place. Similar basalt columns appear across the globe, from Gilbert Hill in Mumbai to the Svartifoss waterfall in Iceland.
