Herdla – glacial deposits
The shift in the landscape is striking between the barren craggy moors north on Askøy and the green fields of Herdla, which has the county's biggest farm. The majority of Herdla, such as the island appears today, is a gift from the glacier: The glacier that advanced here over 12,000 years ago stopped at the northern tip of Askøy and took its time building up the moraine on Herdla. Since then, Herdla has been under continual transformation. The re-organisation of the loose sediment deposits continues today.
Herdleflaket
Spring, summer and autumn, there is bird life on Valen, and the tidal zone is especially attractive. Out on Herdlaflaket, you see ducks and other diving birds all year round, but most in winter.
Lysekloster- The monks and nature
Lysekloster was the largest agricultural property in the country when it was phased out during the Reformation in 1537. In its prime this cloister encompassed two-thirds of all the farms in Os. The monks introduced and cultivated new plant species and it was probably they who stocked the waters with fish not indigenous to the area. This legacy from the Middle Ages has left a lasting mark.
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.
