I was exploring Kazakhstan in Google Maps satellite mode and these yellow areas caught my eyes:

There are numerous lookalike lands when you zoom back.

First I thought these are small deserts because of their yellow color. But when I zoomed in I found they are very white; so the new thought was that these are snow and ice glaciers. But this one I published its image has a 22 miles lrngth and most of them have trees in them. Can it still be a glacier?

Also, a minor question: What are the small circles just to the right? They seem to be man-made and industrical.
