As of today, peak season now, through ~August 31. Earth Exhibit tracks the live conditions and flags it the moment it is on.
Fingal's Cave is a sea cave on the uninhabited island of Staffa in Scotland's Inner Hebrides, formed entirely from hexagonally jointed basalt columns created by the same Paleocene lava flow (approximately 60 million years ago) that produced the Giant's Causeway in Northern Ireland.
The cave extends roughly 70 meters (230 feet) into the island, with an arched entrance over 20 meters (66 feet) high and 12 meters (40 feet) wide, its floor submerged under seawater.
The perfectly geometric columns line the walls and ceiling like organ pipes, and when Atlantic swells enter the cave, they produce deep, resonant booming sounds that echo off the columnar basalt, creating natural acoustics often compared to the interior of a cathedral.
The effect so moved composer Felix Mendelssohn when he visited in 1829 that he wrote The Hebrides Overture (also known as Fingal's Cave), one of the most celebrated pieces of Romantic orchestral music.
The cave is accessible only by boat from the Isle of Mull or Iona, and visitors can walk along a causeway of broken column tops to the cave mouth when sea conditions permit landing on the island.
