The great historic barrier of the Caucasus Mountains rises up across the wide isthmus separating the Black and Caspian seas in the region where Europe and Asia converge. Trending generally from northwest to southeast, the mountains consist of two ranges--the Greater Caucasus (Russian: Bolshoy Kavkaz) in the north and the Lesser Caucasus (Maly Kavkaz) in the south. Mount Elbrus in the Greater Caucasus range, at 18,510 feet (5,642 metres), is the highest peak. The watershed of the Greater Caucasus, the backbone of the system, traditionally has been part of the line dividing Europe and Asia.
