Whoever wanders the mountain plateau will form time to time hit upon old mountain summer farms, with solid old stone sheds, half sunk into the ground; a building tradition that has roots into prehistoric times. When we have been satiated with untouched Nature, it is somewhat comforting to come upon the old mountain chalets - they represent a type of human encroachment that we not only accept, but appreciate. They arouse a feeling of recognition and are a distinct witness to how people in the rural communities have made use of even the most remote resources.
The Ruff lek on Langvassmyrane is the only known phenomenon of its kind on Hardangervidda. Every year it attracts hens from the whole plateau. The marsh is also the richest wetland in the county. This green oasis is located in a rocky moraine landscape a few hours walking distance south of Dyranut.
