The Pioneer League cities are sort of divided into Montana - Great Falls, Helena, Missoula, Billings - and Utah/Idaho - Orem, Ogden (both Utah), Idaho Falls (Idaho), and Grand Junction (which is in Colorado, but near the Utah border). The Montana sites are all around 3,000 feet in elevation. The other cities are around 4,500 feet in elevation. Colorado Springs is 6,000 feet. Most of these cities are pretty dry as well, which I'm guessing makes the ball even more lively. I really don't know the difference in playing at 3,000 or 4,500 or 6,000 feet. However, I lived in Colorado for five years, and I can say that the difference between 3,000 and 6,000 is quite pronounced when it comes to things like hiking. How much difference for baseball players - I don't know.
