Some mountains have rounded shapes, while others have steep slopes and sharp edges. Ulvanosa (1246 mos.) has both. The forms reflect the type of bedrock below, and the forces that were in effect when they were formed.

The oceanic crust of the North Sea was subjected to a lot of stretching both in Permian and Triassic times, and later in the Jurassic. This stretching resulted in the North Sea collapsing in and also to large faults forming west of Hordaland and on the mainland. Austefjorden in Sund follows one of these faults.
When the workers came to Kollsnes to start on the work with the landing for the gas terminal from the Troll field in the North Sea, they found the ruins of an old farm mill at Kvernapollen.

Mangerite is a rock type that was first made famous in a treatise by the Bergen geologist Carl Fredrik Kolderup in 1903. The rock type got its name from the place where it was found, and has made the Mangerud name well known around the world, at least among geologists.
Siggjo is a cone-shaped, volcano-like mountaintop in the part of Hordaland where one finds the best preserved volcanic rocks. The rock types originate from one or several volcanoes that spewed out glowing lava and ash. But, the shape of the mountain, as it appears today, formed later and by completely different forces.
