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 majority of Huglo is bare rock. A bit of dwarf pine forest is the only vegetation able to put down roots. Along the west- and east sides, to the contrary, the landscape is unusually green and lush. The reason lies both in the bedrock and in the ice that covered the area 12 000 years ago.
One of the biggest black alder forests in the country is in Hystadmarkjo. Along the well prepared trail through the forest you can experience an exceptional nature with an unusual abundance of exuberant plant species. But what has laid the foundation for this richness?
The pit saw on the property of the farm Valvatna, is the origin of the name Sagvåg. The sawmill is mentioned as early as 1564. The name of the place at that time was Fuglesalt, but soon there is only talk of Saugvog.
