I spent a few days on the train in Kazakhstan in 2012 - went Moscow-Shymkent-Almaty-Urumqi (on my way from London to Osaka). It was striking looking out across the steppe and seeing a line of telephone poles, and then a completely empty landscape all the way to the horizon. The baths in Almaty were wonderful too.
The descriptions in this thread and your photo are interesting because you don’t need to travel all the way to Kazakhstan/etc like most commenters. In Wyoming/Colorado/Idaho/Montana you can drive for tens of hours and see the exact same thing!
Edit: the kind of scene I'm talking about: https://www.amazon.co.jp/photos/share/8PiwLfaaWMNCyULYDTAvy1...
