 Sinkholes, caves and caverns, disappearing streams, hummocky hills, and terra rosa (residual red) soils in the valleys are distinguishing features of a karst landscape; all these are present in Jamaica.To the west of the mountains is the rugged terrain of the Cockpit Country, one of the world's most dramatic examples of karst topography.The Cockpit Country is pockmarked with steep-sided hollows, as much as deep in places, which are separated by conical hills and ridges.
