Input: Question: How many different countries are the Dinaric Alps in?

The highest peak is Nadkrstac at . Geologically, the Vranica range is part of the Dinaric Alps and formed largely of secondary and tertiary sedimentary rock, mostly limestone. Notable peaks are Nadkrstac (2110 m.), Locika (2106 m.), Rosinj (2059 m.) and Scit (1949 m.). Thick shrubs of Pinus Mugo replace mixed forest -mostly beech- above 1400 m.

Streams that source from these mountains are the Dragača in the east, the Vrbas in the west.
