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 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.

Winter in Rocky Mountain National Park

Although the season is officially still Autumn, at the higher elevations of Colorado it is winter. I drove to Rocky Mountain National Park on a sunny Sunday morning. It is only an hour from Boulder, Colorado. The first stop was to get a picture of the “Chapel on the Rock” with Mt. Meeker in the background. Then it was into the park to get more pictures. Winter view of the Big Thompson River in Moraine Park; Winter Trail to Storm Pass along road to Bear Lake; and a Winter Panorama of Longs Peak taken along Colorado Highway 7
