Wind-sculpted snowdrift

I noticed this snowdrift up against our fence late this afternoon—and would love to learn more about the physics behind the beautiful swirls and ridges of sand dunes and snowdrifts.  I’m sure it has something to do with the granular nature of sand and snow, both of which are solids yet flow like liquids.  But that’s about all I know 🙂

    That’s pretty! It has been snowing here steadily for the last few days and your photo looks a lot like our fence did a couple of days ago. I had never thought about the physics behind the drifts until I read your post.
