Ust-Pinega
Ust-Pinega takes its name from the mouth of the Pinega, where that river joins the Northern Dvina above Kholmogory. The confluence joins the long Pinega valley to the main waterway leading to the White Sea. A place named Pinega appears among the northern river settlements in a charter of 1137, reflecting the early importance of these waterways to Novgorod's trade and collection of tribute.
