I recently presented a session on teaching electricity at the Utah Science Teachers Association Conference. On my way home, I did quite a bit of photography of the snowy landscape, but one roadside slope caught my eye. Driving past, I saw something that I had only seen in books, and a few recent weather articles. Snow rollers! They are usually quite rare, and of the hundreds of snowy road cuts that I passed on the drive home, this was the only one that had them.
