A few nice Rocky Mountains images I found:
Epcot – Rocky Mountain Waterfalls

This area inside the Canadian pavillian is a hidden treasure of peacefulness. It doesn’t attract huge crowds and the waterfall sounds are very relaxing. Also, it always seems about 10 degress cooler, just like the real Rockies.
