I see a lot of interest in Viking colonization of North America, but why not colonize further to the east than they historically went? If they went around the Urals along the coast, they would be in the West Siberian Plains and use the Ob and Yenisey as their inland water way. The route is a lot safer than going to North America, the indigenous people had similar level of technology as the Americans, and the Irtysh river go as far south as western China.
