Located midway between England and Northern Ireland, the Isle of Man is a small island with a complex history. Geologists have studied and reported on the Isle of Man since the nineteenth century, making it a popular destination for rock hounds. Roughly 50 kilometers (30 miles) from northeast to southwest, the island preserves rock layers dating back hundreds of millions of years. While most of the rocks are covered by soil, some rock layers exposed at the surface, along the coast, and in quarries have shed light on this island’s assorted ancient landscapes (via earthobservatory)
