The different bedrock types that got shoved in over Hordaland in Cambro-Silurian times still remain, layer by layer, almost like a cake. But at Kvamskogen the cake has been turned upside down.
At Salthamaren in Vangdalsberget it is thought that salt was burned some time in history, and deep layers of coal in the ground show that fire has been made up here several times. But they were hardly salt-burners, the first people who stopped here. Some of them carved figures into the rock. On top of the rocky outcrop, furthest out on the cliff, a group of Stone Age hunters carved animal figures. More than 1,500 years later Bronze Age farmers drew ship figures at the foot of the rock. Both these works of art - some of the oldest in Hordaland – are still visible, carved in the rock at Salthamaren.
Folds are to be found everywhere in the remains of the Caledonian mountain chain. Some were formed during the collision with Greenland, others stem from the time when the mountain chain collapsed. Few can compare with the giant fold that remains in the mountain area around Tørvikenuten, Vesoldo and Hellefjellet.
