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.


The folding of the bedrock can be compared to the  folding of a paper.
