The bedrock rose from the sea over 3300 years ago, and the oldest figures may be just as old. Where the lines from different figures overlap, we can see which were carved first. The oldest images show elks and small whales – probably porpoises. The more than thirty boat motifs were carved over the animal images. They depict boats made from animal skins stretched over wood frames. The motifs belong to our oldest rock art tradition called hunters rock art, or the Northern rock art tradition.

The hunters, trappers and fishers left their figures behind once they paddled on. Other groups paddled past the islet in the middle of the fjord and engraved their own figures in the same place.

The latest petroglyphs are small pits and circles carved into the rock. The motifs belong to a new pictorial tradition, made by people who farmed grain and kept livestock. Their pictorial world is connected to this new way of life. At Evenhus, hunters rock art and agrarian rock art meet. For hundreds of years, people with different lifestyles expressed their pictorial traditions side by side in the landscape.
