Ustaoset

Ustaoset is situated 990 m (3,250 ft) above sea level and is the finish for the cross country ski event Skarverennet.

Ustaoset has a rail station on the Bergen Line running between Geilo and Finse, as well as a hotel and mountain resort cabins.

Families from both cities built cabins, some now over one hundred years old, from which they could ski in the winters and hike in the summers.

Reaching the summit of Folarskardnuten, at 1,933 m (6,342 ft) the highest point in the region, on skis or on foot is a notable achievement.

Some episodes in the book feature police detectives from cosmopolitan Oslo coming to conduct investigations in the far more primal mountain environment of Ustaoset.
