Dawn Winding Mountain Road, Quiraing, Isle of Skye, Scotland

Dawn on a rugged road

Take a good look at this winding road, because it might not appear quite the same next season. Known as the Quiraing, this cluster of cliffs and crags on Scotland's Isle of Skye formed from an ancient landslide—and the ground is still moving. Sure, it's only an inch or two a year, but that's enough to make road repairs necessary on a regular basis.While the collapse that created these crags was indeed massive, it was nothing compared to the colossal rumblings that built the isle's bedrock. The basalt backbone of the Trotternish peninsula formed from lava flows that belched from a once extremely active volcano—one of several that formed the Isle of Skye's distinctive rock formations and coastal cliffs, but have long lain extinct.
