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.
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.
