Vetza
The Vetza is a small river of the wooded uplands west of Mozhaysk. It joins the Sezha, whose waters flow onward into the Vazuza and the upper Volga. Its valley lies among the streams that cross the old border country between the lands of Smolensk and Moscow. Fields and woodland share the rolling ground, while the river belongs to a drainage network that leads northward to the Volga rather than south toward the Oka.
