mountains
Mountains are not the signature feature of the Russian landscape. However. If when we say "Russian" we have the entire empire in mind (as we almost always do at Imperiia) rather than something more like the Russian Federation... it is a different story. Several remarkable ranges - wholly or in part - fell within the boundaries of the empire, including the Carpathians, the Caucasus, and the Eastern Range of Kamchatka (home to the highest volcanic peak in the northern hemisphere).
