Butyrskoe
Butyrskoe stands beside Lake Ostrovnoye in the country west of the Ob. The lake and the nearby Kasmala valley attracted Russian surveyors seeking a site for a new silver-smelting works in the 1760s. Settlement spread through the district as the Kolyvan-Kuznetsk defensive line and the Altai mining enterprises extended their reach. In 1780, a peasant household from Morozovo established the village of Butyrskoe on the lakeshore. Other families followed, forming a small farming community within the growing network of villages on this Siberian frontier.
