100% yurt.
Yurts in cold climates is a thing. Sometimes they just have a smoke hole in the roof instead of a chimney. All the pictures are at weird angles, they're printed on a ball! :-)
The geometry of the ball isn't relevant - the "smoke" as depicted is going out of the side of the "yurt" at a right angle and continuing in that direction. That's not how smoke works. And the "yurt" itself is clearly depicted as a wedge. With the "smoke" attached to it as a cylinder.
If it's supposed to be a yurt, one has to ask why someone went through obvious effort to make a yurt look as much like an axe as possible.
