<Tr> <Td> </Td> <Td> 1914 map showing the boundary along the Manych River, placing Stavropol Krai in Asia </Td> </Tr> <Tr> <Td> </Td> <Td> Miles Clark in his 1992 "circumnavigation of Europe" followed the White Sea--Baltic Canal until Lake Onega and the Volga--Baltic Waterway to the Rybinsk Reservoir before joining the classical boundary along the Volga and Don rivers . </Td> </Tr> <P> The modern border between Asia and Europe remains a historical and cultural construct, defined only by convention . The modern border follows the Aegean Sea, the Dardanelles - Sea of Marmara - Bosphorus (together known as the Turkish Straits), the Black Sea, along the watershed of the Greater Caucasus, the northwestern portion of the Caspian Sea and along the Ural River and Ural Mountains to the Kara Sea, as mapped and listed in most atlases including that of the National Geographic Society and as described in the World Factbook . According to this definition, Georgia and Azerbaijan both have most of their territory in Asia, although each has small parts of their northern borderlands north of the Greater Caucasus watershed and thus in Europe . </P> <P> Though most geographic sources assign the area south of the Caucasus Mountain crest to Southwest or West Asia, no definition is entirely satisfactory, with it often becoming a matter of self - identification . Cultural influences in the area originate from both Asia and Europe . While geographers rarely define continents primarily politically, Georgia and to a lesser extent Armenia and Azerbaijan are increasingly in the 21st century politically oriented towards Europe, but Armenia has a great cultural diaspora to the south, and Azerbaijan shares a cultural affinity with Iranian Azerbaijan as well as with the Turkic countries of Central Asia . </P>
