region as sheep herders. Names of various Albanian tribes (Hoti, Gruda, Kelmendi, Kastrati, Dukagjini, Shkreli, Shala, Nikaj, Krasniqi, Gashi, Kuci and Rugova) refer to their geographical locations within the range. Geology The Accursed Mountains are a typical Dinaric karst high mountain range with a pronounced steep topography and glacial features. Maximum relief differences of are found in the Valbona, Grbaja and Ropojani and Cem valleys. Overhanging walls and ridges forming pointed peaks are typical of the western and central Accursed Mountains. The eastern mountains are less rugged with lower relief. The valleys show characteristic effects of Pleistocene glaciation. Most of the area was modified by glacial activity with karstic areas in the western parts. The range was formed by the folding resulting from the collision of the African and Eurasian plates. Nowhere in the Balkans have glaciers left so much evidence of erosion. After the Alps, these mountains are the most glaciated in Europe south of the Scandinavian ice sheet. They have very steep limestone slopes with abundant karst features. The Accursed Mountains are a large, rugged, pathless range. It is one of the rare mountain ranges in Europe that has not been explored entirely. In some areas, the Accursed Mountains run almost parallel with the Šar Mountains in North Macedonia, Albania and Kosovo. This tectonic crash produced the unusual zig-zag shape of the range and also their curving from the dominant Dinaric northwestern – southeastern direction toward the northeastern one. In the western and central parts of the range the composition of the mountains is of mainly uniform with Mesozoic limestones and dolomites of the Jurassic and Cretaceous ages. In the eastern Accursed Mountains in addition to the limestone and dolomite series, there are rocks from the late Palaeozoic and Triassic periods, medium-Triassic volcanic rocks and Jurassic metamorphic rocks. The Kalktafel is cut deeply with valleys in a variety of rock blocks of the mountains north of Përroi i Thatë, the Biga e Gimajive south of it, the Jezerca block between Shala and Valbona valley, the massif of the Maja e Hekurave, the plateau of the Maja e Kolats north of Valbona and Shkëlzen northeast of Valbona. The valleys were formed by glaciers which created very steep walls and hollows up to deep. The south wall of the Maja Harapit is high, making it the highest rock face on the Balkan Peninsula.
