Olyokma Upplands

Forested ridges and deep river valleys divide the highlands between the Vitim and Chara in eastern Siberia. Streams from these mountains reach the Lena through different branches of its vast basin. The Kuanda flows toward the Vitim, while the Chara joins the Olyokma farther east. Larch woodland covers many valley slopes, and winter snow and ice persist through the long cold season.
