|a strip of land, now in Russia, between the Gulf of Finland and Lake Ladoga: annexed by the former Soviet Union after the Russo-Finnish War (1939--40)|
neck of land lying between Lake Ladoga (east; in Saint Petersburg oblast [province]) and the Gulf of Finland (west; part of the Baltic Sea). The isthmus shows evidence of ancient glaciation; its long, winding morainic hills, which reach an elevation of about 570 feet (175 m) in the south, are separated by countless lake-filled hollows and swamps, and its soil, sand, and rocks reveal glacial deposition. Much of the region is covered by evergreen forests.
