This top one is a Green Hair Streak, very flashy in contrast to the reddish-brown soil. The bottom one I'm not sure of. When I first spotted it, I thought it was a cabbage white til I got closer and saw the different wing shape and more extensive black markings. It might be a Rocky Mtn Parnassius (Parnassius smintheus) .
My favorite butterfly ID site has moved. For anyone who likes to look these things up, the USDS site is now hosted by the Montana State University at: http://www.butterfliesandmoths.org
