There are two thick canvas covers, one underneath the decorative outer cover which keep the yurt waterproof.
This show what can be done with a little landscaping.
Photos showing our red and blue gers, we can also supply green see above door. The first photo shows the thick lambswool underlay which makes the gers warm and cosy in winter and cool in summer. The glass dome to see the stars through. The framework structure and the thick green canvas cover that sits under the outer decorative cover which makes the ger very waterproof. The round structure ensures that the yurts/gers can withstand near cyclonic conditions providing the door is closed so the wind can't funnel into the yurt. The photo on the bottom left shows the trellising framework.
