Heterogeneous Nucleation

As well my husband knows, I could look at rocks for hours. And if nature should glaze them in a layer of ice, he knows he might as well pull up a stump!

The pinks, greens, reds, and beiges of these rocks are stunning on a calm summer day submerged in the cold waters of Waterton, a mountainous park in Alberta, Canada. But on this winter morning when ice formed around nucleation sites, perhaps in this case, grains of dust or surface irregularities, the rocks were swathed in intricate lace patterns. Confirming, once again

In every walk with nature one receives far more than he seeks.
