We discovered hoar frost on top of the ice on the West Branch of the Nezinscot River yesterday. Hoar frost is similar to dew. It forms when the air is super-saturated with moisture and the surface temperature is below freezing. The individual crystals are small and form from a single seed crystal and if left undisturbed c
an grow into beautiful formations. After several calm, cold nights, these crystals in a protected area of the river and on ice that was about 6 inches thick had time to grow into shapes that looked like ferns, feathers and lace.
