Dalskarvatnet–Dyvikvågen
Many of the fossils one finds on Stord are related to fossils of the same age found in North America. Scientists thinks this indicates that the bedrock on Stord was much nearer to America at that time than today.

Kattnakken–Stovegolvet
The highest mountainous area on Stord, including Kattnakken, Midtfjellet and Stovegolvet, has more in common with the mountainous terrain on the mainland than in the low coastal landscape of Sunnhordland. The volcanic bedrock together with the erosive powers of nature has resulted in a unique plateau landscape.

Ulven
In the region of Ulven phyllite occurs with Hordaland's youngest fossils, and a beautiful quartz conglomerate. The phyllite and conglomerate got squeezed into the bottom of an ancient oceanic crust, made of gabbro and greenstone, in the heart of the Caledonide mountain chain.
