I will be in NYC in the first week of January. Since I prefer sightseeing and not doing classical winter activities (ski etc), I wonder what sightseeing activities are available in winter in the Rocky Mountains?

Many good questions generate some degree of opinion based on expert experience, but answers to this question will tend to be almost entirely based on opinions, rather than facts, references, or specific expertise.

Unless you are interested in skiing, there are limited activities, and you will miss a lot.
All the major national parks (Rocky Mountain NP, Yellowstone, Grand Teton, Glacier etc) will be closed or partly closed. As will many hotels, most scenic roads/passes and so on. You can look for individual information about each park and its surroundings here.
The majority of this infrastructure will be closed until April (or later).
