A geophysicist in the 1970s doing a geophysical survey of the border between Finland and Norway discovered that Finland’s highest elevation point was on a slope directly on the border - and the peak of that mountain was actually just a couple meters across the border in Norway. He then proposed the idea of having Norway agree to give Finland this mountain peak as a present, eventually walking across all of Norway to lobby to give them the mountain and settling on 1917, the 100th anniversary of Finland’s founding as a nation. That would give Finland a new highest point and a new mountain. Once the idea was around, they began having to figure out how to actually go about legally making this plan happen - how do you convince a country to give up a mountain?
