I have looked through the pictures of moths in CO and in RMNP. Found similar ones but none with the same looking spots.

Larimer County Colorado

I think it is the black witch. A fact sheet on this is at: https://webdoc.agsci.colostate.edu/bspm/2018/BlackWitch.pdf  Lots more pictures at: https://bugguide.net/node/view/23779/bgimage

Very large moth - the one with the largest wingspan one will find in Colorado.  Doesn't reproduce in the state and does not survive  between seasons.  It is a migrant that periodically gets blown up from Texas and points south.  A weather pattern a week or so ago seems to have pulled some into the state.
