The Sukhona Route and Veliky Ustyug: This route crosses the center along the Sukhona and Vychegda Rivers which join near Veliky Ustyug and links Novgorod to the Kama River and Kazan. From Veliky Ustyug one can go west up the Sukhona, east up the Vychegda, northwest down the Northern Dvina to the White Sea, or south up the Yug River and down the Unzha River to the Volga and Kazan. From the upper Sheksna south of Lake Beloye, portage to the ? river and downstream to Lake Kubenskoye. (This is now the Northern Dvina Canal. Vologda is just south of lake Kubenskoye.) From Lake Kubenskoye east northeast down the Sukhona River about 400 km to Veliky Ustyug where the Yug River comes in from the south. The river now gains the name of Northern Dvina and flows about 60 km northeast to the modern town of Kotlas where the Vychegda River comes in from the east. From Kotlas east at least 400 km up the Vychegda to its headwaters west of the Urals. From here portage north to the Pechora or south to the Kama, both of which lead to passes over the Urals.
