@UralAdel these pictures are simply beautiful. Even I plan to visit Yellow Stone National Park upon my next visit to US.
I would also take this opportunity to remind you that currently there is an image limit on Connect. You can only post 1000 pictures. So you should choose wisely what pictures you want to show on the post. Rest of the pictures you can upload on Google Drive and share the link on the post…
Hope it helps
Keep Travelling and Keep Sharing 
Hi @UralAdel ,
Thanks for posting your wonderful photos! Can you tell us more about this place? Why is it called Yellowstone and what is it known for? When did you visit this place and how did you travel there? Did you stay overnight? What is your favorite thing about it?
It looks absolutely amazing the lake and the mountains! I have already a few national parks on my list that I need to see! Have a look at How do I write a post on Connect and thank you @Kavita1 for reminding of the photos limit.
Yellowstone is my favorite National Park. Especially the geysers are impressive! Thank you for posting those pictures. Brings back memories.
