Jackson Hole, Wyoming.... it's not just a ski destination.  I'm not much of a skier but I've discovered that you shouldn't rule out popular ski destinations during spring & summer.  In my opinion, they are just as beautiful (if not more) during the warmer months.  I visited Jackson Hole during Labor Day weekend 2007 and it truly took my breath away.  I had a basic point and shoot camera on this trip and was able to capture some amazing shots.  It's not hard with that amount of natural beauty surrounding you.
