I visited Silver Lake Sand Dunes State Park yesterday anticipating the graceful dunes I had seen on previous visits. (See “The Sand Dunes at Silver Lake State Park.”) But, instead, the sinuous dunes I had anticipated looked more like sedimentary rock that had been disturbed by some incredible force.
The dunes freeze in the winter, so only a fine layer of grains of sand at the surface are free to blow with the wind. I suspect that the formations I saw were caused by the expansion and contraction of the ice crystals in the sand as our crazy temperatures have swung wildly this winter. Having anticipated smooth dunes, I needed to shift gears. I decided to go in close and photograph the formations left by the ice and the wind.
