Matti Braun - Kola
On Russia’s Kola peninsula, near the Norwegian and Finnish borders, unique rock formations have remained virtually unchanged for more than two and a half thousand million years.
in 1970, the peninsula was therefore chosen as the site for the so-called Kola Superdeep Borehole.
By 1994, it had been drilled to a depth of more than 12,000 metres, making it the deepest borehole in the world.
At the same time, Kola is threatened by the environmental impact of radioactive waste, both from civilian power plants and from the spent fuel rods of Soviet nuclear submarines.
