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.
