== Geography == The name Prenj is derived from Perun, supreme deity of Slavic mythology. Geologically, the Prenj range is part of the Dinaric Alps and formed largely of Mesozoic and Cenozoic sedimentary rock, mostly limestone and dolomite with notable characteristics of a karst landform. Due to subterranean drainage, Prenj is relatively dry with few water sources, just a few tiny and one large lake and some small streams that get waters from these mountains, such as Konjička Bijela, Baščica, Glogošnica, Mostarska Bijela, all tributaries of the Neretva. Beneath the plateau Borci on the northeaster slopes and Crna Gora mountain on the east, at the end of the deep ravine of Boračka draga a large glacial lake, Boračko Lake, formed during the expansive process of glacial erosion. The lake is exorheic and belongs to Prenj's watershed, as it is refilled with a stream originating on the mountain and flowing through Boračka draga into the lake's southwestern shore. Šištica river is the lake's outflow.
