Between the Wind Rivers and the Front Range of Colorado is the Great Divide Basin - it's a very difficult region for animals to simply migrate across - especially animals specific to colder, wetter climates - and most especially without any great reason. People can, and do release wolves into Colorado in hopes to reintroduce them. I believe that's where most of the sightings are coming from. Many times these wolves are wolf/dog hybrids. I've had complete strangers admit to as much. I very much suspect any sightings of wolves in CO though, almost as much as I do grizzly bear.
