Insoluble flysch deposits have formed a very harsh terrain. In the region, the carbonatite rocks are dominant and only in the villages of Valbona and Dragobia the schist nucleus of the Alps appear. Hydrology The region is characterized by a highly developed hydrographic network represented by the water basins of the lake of Shkodër and of that of the rivers of Drin, Buna, Shala and Valbona. The park is situated along the course of the Valbona, the longest river on the Albanian Alps at . The river begins at the southern slopes of Maja Jezercë on the eastern section of Valbona Pass and flows until it reaches the village of Valbona. At the end, the river, which until then was continuing through a narrow u-shaped valley, becomes the Fierza that is mostly surrounded by high mountains. It flows away through the village and continues flowing towards Dragobia. Valbona River is a tributary of Drini River, which drains into Adriatic sea. Deduction from the peaks of the mountains of Rragami and Ceremi, is impulsive, full sound of effervescence for its terrain topography. At Shoshan's canyon, Valbona's river narrows sharply and creates the image of the rocks being cut as with a knife. Water is clean, bright and highly transparent up to 1 m depth. Frequent rain precipitations make this river unnavigable. The Xhemas Lake is a natural basis, which is supplied by the water that steams inside this base from the depth of rocks and reaches up to 3 m depth in winter. It has an area about 500m2. Lake has an altitude of 770 m above sea level. There is the main road close to it that goes from Dragobia to Valbona, exactly in "Quku i Dunishes", in the left of pedestrian road which arrives in the forest. Xhema lake has very cold clear water, rugged limestone cliffs and is surrounded by beech trees. Shortly after the source of Valbona's river, colliding with rocks, is created a 50 metres high waterfall, which disappears at Rrogami gritty earth for about 5 km and then stems again at Valbona village. The Shoshani Source is one of the biggest water sources of the Balkan peninsula. It is located at the entry of Valbonë Valley and is continually visited by alpine nature lovers. The source provides potable water for the entire Tropoja District and its water quantity is equal to the half one of
