Halsnøy

Hadde ikkje Hardangerfjordbreen mot slutten av istida rykt fram over fjordbotnen, ville Halsnøy ikkje eksistert som éi øy, men som mange småøyar. Breen skuva framfor seg så mykje leire frå havbotnen at Brattåsen, Toftåsen, Landåsen og Svartaberg vart samla i eitt landområde.

Ølve

Ølve has a special soil type. Here one finds an extra hard clay soil. This is especially noticed by those who work with excavating for building foundations and the like. Often it is necessary to use especially big digging machines and sometimes even dynamite in order to break up the compact masses. The reason for this is the growth of the glaciers toward the end of the Ice Age: The clay, that was first deposited in front of the glacier, came under great pressure when the glacier later grew and slid out over the clay.

The Vosso river network

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.
