Ötzi was found on a mountain ridge, at the border between Austria and Italy. After the First World War, Austria had to give the southern part of Tyrol to Italy; it is now known as Trentino-Alto Adige/Südtirol. At the time, the border was fixed on the watershed of that ridge. The problem with this is that the ridge is usually covered by a glacier, which was also the case in 1919 and 1920. When the border was fixed, the expert team supposed that the watershed was straight below the glacier. The border was fixed that way in 1922 and 1926. The body was found on the Austrian side of the slope. Measurements were done in 1993; they showed that the border is in fact 93 metres from the place where Ötzi was found, on Italian territory. Since 2006, there is a new contract which fixes the border between Austria and Italy: In the case of glaciers, the border is taken on the surface of the glacier, and no longer on the watershed below. This also means that the border is now variable, and depending on the state of the glacier, the place where Ötzi was found is in Austria or in Italy.
