A nice UNESCO cover from Montenegro, with 2 stamps dedicated to the "Durmitor National Park". Durmitor is a limestone massif that is part of Dinaric Alps. It was shaped by the glaciers and is traversed by river canyons, of which the Tara River Canyon has the deepest river gorges in Europe, at about 1,300 meters. There are 18 glacial lakes in the park, the largest is the Black Lake. Durmitor is also an important biodiversity spot. Following the inscription to the UNESCO World Heritage List in 1980, the borders of the site were modified in 2005 to be in line with the national park boundaries.
