Outdoor Winter Nature in Colorado: Rocky Mountain National Park.

The sky was clear, so drove from Boulder to Rocky Mountain National Park. The roads in the park are open, so I spent another day taking pictures in this great National Park. It is cold, and the river is frozen. I am getting good use out of my Golden Eagle Pass.

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.

Winter in Rocky Mountain National Park.

The main road on the east side of the park was open so I spent the day. It was cold and windy, and a new storm appeared to be building. It has been interesting to watch the seasons in the National Park.
