Backyard Winter Night Sky in New Jersey. Moon Ring and Orion.

The 22° Halo around the moon is caused by refraction of ice crystal high in the atmosphere.

Outdoor Winter Nature in Colorado: Lily Lake in Rocky Mountain National Park.

During a winter visit to Lily Lake in Rocky Mountain National Park, I observed these two folks out in the middle of the frozen lake. What do you think that they are doing? To give you a hint, they are not ice fishing, but it does have to do with fish under a frozen lake. Please reply if you think you know what they were doing.

Winter Nature in New Jersey.

Great Blue Heron and a pair of Mallard Ducks in the pond at the nearby Sourland Mountain Preserve. I guess they decided to spend the winter here rather than in Florida.  Some years this pond freezes over.
