Crazy!! you are right! It is a snowfield blown into those formations by the wind. They are very thick and strong on the bottom wider parts, however quite brittle on top (except when you really want them to break so that you and your enormous pack can get through - then they get stubborn and do not budge!!) Beat climbing up deep, steep scree though.
Thank you for your comments on my photos and thanks for sharing yours.
