Three Wintry Phases
Going out on a limb with utmost confidence, we can say that three different products of winter weather appear here simultaneously. Freezing rain encased the twig and buds in ice, followed by an accumulation of snow. Small, spiky formations sticking up from the snow's otherwise smooth surface are composed of hoarfrost, deposited during a brief episode of freezing fog.
