I’ve posted images from Hop Brook in Belchertown. This is my first from Hop Brook in Amherst. During our warm temperatures lately, the top of the frozen brook melted leaving a layer of water above the ice. When the water refroze over night, it created a crust with an air pocket between the two layers of ice and lots of bubbles formed overnight during the refreeze. The white patches are fissures in the crust.
