Ust'-Kabyrza
Ust-Kabyrza stands near the mouth of the Kabyrza, where it joins the Mras-Su in the forested mountains of Shoria. The river valleys were home to Shor communities, whose territories extended along the Mras-Su and up the Kabyrza. An old route crossed this mountain country between the Sagay and Altai steppes. The meeting of the rivers offered a way through a region of wooded slopes and narrow valleys.
