Селенга
The Selenga River basin is a semi-arid region, that is 280,000 km^2. It is part of the Arctic Ocean Basin and is located in northern Mongolia. Stone implement artifacts found on the Selenga River at the end of the 19th century, have now been used to form the link between Native Americans and their ancestors in East Asia. The climate of the Selenga basin is influenced by a powerful Siberian anti-cyclone. The weather consists of harsh winters and warm summers, with the river freezing from November to April.
