Major shipping routes are indicated by red and blue solid lines, with standard directional arrows. This map is oriented to the southern and southeastern portions of the lake, with the Angara River on the lower right (and the main regional city of Irkutsk toward the bottom) and the Selenga River on the other shore toward the upper left. It was drawn in 1799 by two geological and mining specialists, Frolov and Kopylov, who were members of the Nerchinsk Expedition and compiled a series of regional maps. The map shown here, centered on the southern portion of Lake Baikal, highlights the route of ships that carried shipments of lead between two major rivers on opposite sides of the lake, the Angara and Selenga.
