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.
If you want to be on your own for a long day in a magnificent deciduous forest in demanding terrain, then HOLMESDALSBERGET is the right place. This is a big forested area by Matres Fjord in the southwestly part of Kinnherad. Here, we find one of the largest deciduous forests in Hordaland. The forest stretches over several kilometres.
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.
Fjøsanger is known among ice age researchers from around the world. Under an excavation in 1975-77, geologists from the University of Bergen found layers from the last interglacial, ca. 115 000 to 130 000 years old.
Some of the giant trees in Hopslia north of Holme Fjord are as much as thirty metres high. Elm and ash are the most common, basswood somewhat rarer. Relatively soft bedrock, good growing conditions and enough light, help them to thrive just here.
