Sign 5. The bedrock

The bedrock tells of large-scale geological processes that took place about 470-430 million years ago when Norway and Greenland collided. The bedrock was folded and a great mountain range, the Caledonian, was formed (see figure). It was just as long and just a tall, if not taller, than today's Himalaya.

The Caledonian mountains have since eroded, but the bedrock surface that remains today is a window into what once was. We can, in many places in this area, see the folded mountains in miniature. Try to find examples in the bedrock.
