Dinaric Alps
Croatia proper straddles the boundary between the Dinaric Alps and the Pannonian Basin, two of three major geomorphological parts of Croatia. The boundary runs from the Žumberak range to the Banovina area, along the Sava River. The Dinaric Alps are linked to a fold and thrust belt active from the Late Jurassic to recent times, and is itself part of the Alpine orogeny that extends southeast from the southern Alps. Karst topography is especially prominent in the Dinaric Alps.
