Freezing and thawing are processes that influence plant cover, move enormous blocks, stretche long mounds of earth, break open bedrock and create patterns in stone and earth.
They rest there, all as one, the silent witnesses of Western Norway's saga of creation: Precambrian basement, phyllite and thrust sheet. In the end came the glaciers and sculptured the vast landscape. Along the ground or on the horizon, from bicycle or on foot - the landscape tells its story - and it tells it clearer on Rallarvegen than many other places.
The ice cap that covered the land during each of the 40 past ice ages over the past 2 million years of Earth's history pressed down the crust of the earth - like a finger on a rubber ball. And when the ice finally loosened its grip 11,000 years ago, the earth's crust rose again, most where the ice was thickest, least where it was thin, quickly in the beginning, and later more slowly. To this day, the land in the inner part of Norway continues to rise by perhaps one millimetre per year. By and large, however, the crust in Hordaland has again reached equilibrium after the weight of the ice was removed.
The steep drop by Fossen cliff has been the biggest challenge for those who wished to make a road over Kvamskogen through the years. Leave the car by the monument on the old road and take a walk down to the bend by the waterfall that Bergen-folk call "The bridal veil". Why is there a waterfall just here?
One does not need much imaginationto see that where the river bends down in Røssebotnen, there has once been a lake. The landscape tells this - more clearly than any book.
