English: Demerdzhi, Crimea. A place of frequent fog, haze and special atmospheric and lighting conditions. The rocky valley is formed of the conglomerates of sandstone, limestone, quartzite and pink granite. Like many other Crimean mountain ridges Demerdzhi was formed in Late Jurassic some 150 million years ago but it is believed that some granite magma intrusions are up to 1 billion years old (Tonian Neoproterozoic).
