Ladoga, Indiana Ladoga, Indiana Ladoga is a town in Clark Township, Montgomery County, in the U.S. state of Indiana. The population was 985 at the 2010 census. Ladoga was platted in 1836 by John Myers. Myers invited his friends to help him find a name. He required that the name not end in -burg or -ville and that it would not be named after another town. He chose Ladoga after finding Lake Ladoga on a map of Russia. In 1837, the town's post office was established, which still operates today. In 1840 there were fifteen buildings in Ladoga, including two large stores
Lake Ladoga were connected by a strait or a river outlet at least until the formation of the River Neva, and possibly even much later, until the 12th century AD or so. At 9,500 BP, Lake Onega, previously draining into the White Sea, started emptying into Ladoga via the River Svir. Between 9,500 and 9,100 BP, during the transgression of Ancylus Lake, the next freshwater stage of the Baltic, Ladoga certainly became part of it, even if they hadn't been connected immediately before. During the Ancylus Lake subsequent regression, around 8,800 BP Ladoga became isolated. Ladoga slowly transgressed in its southern part
