Ask mot Herdlefjorden og Holsnøy

Ask- jordbær

Strawberry-growing on Askøy flourished in the beginning of the last century. When gardener Samson Eik took in the type "Seierherren" from Rosendal in 1909 for growing strawberries on Hop, it appeared that the soil and climate in this area was perfect for the mass production of strawberries.

Gullbotnen

Gullbotnen

A barren belt where almost nothing grows, runs through the forest on the east slope of Gullbotnen. But, along the west side of the main road there is a fertile zone that flourishes with several finicky plant types. The contrasts arise from the extreme variations in the nutrient content of the bedrock.

Geologists from all over the world come to study the veined bedrock (the dark stripe in the picture) at Spildepollen.

Spildepollen

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.

Eclogite bedrock at Ådnefjellet.

Eldsfjellet

The eclogites in western Norway were formed when Precambrian basement rocks were squeezed and pressed down under great pressure deep under the Caledonian mountain chain. The process may well have triggered some of the deepest earthquakes the world has ever known. The clearest traces of this drama are found in and around Mt. Eldsfjellet, in peaceful Meland.

Litlandsvatnet

Large quantities of nickel ore have been mined from Litlandsvatnet, between Lonevågen and Hosanger. The discovery was made in 1875. During the period of operation from 1882 to 1945, 4170 tonnes of pure nickel were extracted from 462 000 tonnes of ore, a large production by Norwegian standards.

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.

Garnets at Vågenes

Vågenes

On Vågenes, on one of the prominences out toward Eitrevågen, one finds garnets in anorthosite. The garnets are both older, and not least bigger, than average.

Kjerringafjellet

Bergsdalen

The mountains of western Norway are lovely to wander in. In Cambro-Silurian time it was the mountain itself that wandered. The mountain, or more correctly the bedrock, first moved eastward, then back a bit westward again. All this rocking back and forth in the mountains ended about 400 million years ago.
