Snow bedforms – such as dunes, ripples, and anvil-shaped sastrugi – cover as much as 11% of the surface of the Earth, but their formation is barely understood.

For the past three winters, I’ve documented the evolution of snow bedforms in the Colorado Front Range using time-lapse videos, and produced 1000 hours of the first footage of snow bedform growth and evolution.

How do snow bedforms evolve?

We are now preparing examples, documenting the movement of several types of bedforms, for publication. You can preview the figures below.
