Russia east of the Ural Mountains is vast; there is no other word to describe the enormity of this region of grassland and tundra. Technically, it does not extend all the way to the Pacific Ocean, but it does go from the Arctic Ocean to the Chinese and Mongolian borders. This is not a part of the world well travelled, but it could become so with a good, detailed map. We start in the west at Omsk on the Irtysh River, where the northern and southern branches of the Trans-Siberian Railway line cross each other. I am afraid that most of the cities of the region would not be well known, but I notice Novosibirsk, Irkutsk, and Lake Baikal. This is wilderness with a capital W, a region waiting to be discovered by intrepid travelers. Go for it! You can actually drive across Siberia now, as well as go by train.
