Yes
Parnassius smintheus. I've never seen one as late as September, but it was pretty high up. Looks like you've got two in this shot. You'll find this one listed sometimes under Parnassius phoebus too, but there is a fad lately to split them up into different species depending upon where they are found.

could be Parnassius
This sure looks a lot like the Parnassius smintheus I took at a high elevation on Mt. Evans. Check it out in the guide.
