Across the Interior of Iceland 1983 on netflix

The film is about travelling on horseback across the Icelandic interior on the main route, which once connected the north of Iceland with the shout. This route was the scene of a tragic accident in the 18th century, when young farmers moving a flock of sheep to the North, perished in a snowstorm. For many years following the incident the track was not used, until the 19th century, when Captain Daniel Bruun from Denmark, accompanied by a photographer and a water-colour artist, crossed the difficult terrain, deep rivers, and rocky heights in sun, rain, fog and wind, marking the way with stones laboriously heaped into cairns.
