Skorpo - Polished by glaciers and meltwater
"So many and such big potholes as are found at Eikelandsosen, we don't see other places in western Norway, and as beautifully polished as the mountainside is along the river up to Koldal , one would look a long time to see anywhere else. There is much to dazzle a geologist's eyes. If only these features could bring others the same joy!"
Bays that are shallow far out into the sea, with fine sand and clay, are rare in Hordaland. Where they are found, the reason is usually that the edge of the glacier made smaller advances or stopovers when it calved back at the end of the last Ice Age. This is what happened at Vinnesleira.
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.
There are many river networks out by the coast and they tend to be small and unassuming. The farmer has relied upon the watercourses to run his mill and saw, and it may be that the trout have given him a good source of food in years when the ocean fish failed. In our time, these river networks are being rediscovered for their value in recreation and outdoor life, and several places, tourist trails have been built in order to fully enjoy them.
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?
Deep down between the stone polished phyllite bedrock in Bordalsgjelet canyon, there is a cascading river. In close cooperation with hard polishing stones, the water has carved into the bedrock for thousands of years - and is still doing so today.
The sediment that was deposited from the river Dyrvo has created the fan-shaped delta Rekvesøyane. The bit of land farthest out toward the water gets periodically flooded, especially during snow melt and after periods of much rain.
The Vosso is Hordaland's main artery, she has never run more richly than in our times, and no other river in western Norway carries so much water. The increase in the amount of water comes mainly from hydropower development, due to the transfer of water from other water systems. Climate change can also be a reason that the Vosso carries more water than before.
