Thanks for sharing those pictures, you are very lucky to have taken those. The animal does in fact look like an ermine also known as the short-tailed weasel. In the winter their coat turns white like in your pictures, and in the summer turns a reddish brown. We do not keep track of sightings for them. They are not endangered or threatened in Colorado, however they are elusive and are rarely seen, so count yourself lucky. The link below will take you to our information page on weasels if you are interested in some more information. Thank you for sharing with us.
