2012European Protection of Nature - First Day Cover

On the ninth kilometer of the old road Foca - Miljevina - Sarajevo, in Pirni Do, there are Sandy pyramids. Soil erosion, a long series of years, was created as a result of aggressive loop frosts, summer eat, rain and strong winds. Sculpted figure of interesting shapes are similar to those in Colorado (USA), Dolomites (Italy) and Devil's Town (Serbia). Striated sand pillars rising from its foundations broad and tapering towards the top, and an outstanding geomorphological rarity in these parts. This erosion continues today, so they do not disappear, but on the contrary, increase. Pyramids are a masterpiece of nature.
