[2] By the early Middle Ages, there was already a need to navigate the ocean north of Nordmøre, a long time before 1742, the year Kristiansund became a town.

The most important urban area of Nordmøre in the Middle Ages was the fishing village of Grip, an island in the ocean north of Kristiansund.

He mentions all the mountains on shore: Skarven (on Tustna), Stemshesten, Magnillberget, Freikollen, Quærn-Bierget (an old-fashioned way to spell Kvernberget), and Plak-Myssen.

[3][4] The name Kvernberget is probably a thousand years old, and refers to the mountain's resemblance to a medieval Quern-stone of a form which is still used in North Africa today.

Fishermen working in the sea off of the island and fishing village of Grip navigated by the mountain, which they named after the tool they had at home, the hand mill for grinding corn to flour.
