Week 36 at the Pole
These are sastrugi. Who doesn’t love to learn a new word? Sastrugi are wavelike ridges of hard snow formed by the wind. Visually they are reminiscent of sand dunes but they are not as easily shaped by the wind as sand is. It’s pretty light in this photo, with the sun beginning to rise at the pole, yet the moon is still hanging in there at the moment—enjoy some more of the views.
