It is obviously a combination of cold and snowfall. Crank enough of either one up, and annual snowfall turns into a “perennial ice field,” and if that piles up enough, it turns into a river of ice that starts breaking things. Why are there glaciers in Montana at 9,000’, whereas there are none at 14,440’ at the highest point of Colorado? Why is the largest glacier in the American Rockies beneath 13,000’ peaks in the Wind River Range, but relatively small ones beneath Grand Teton, at the same height, and about 100 miles away? I have often noted that flying a Cub at such slow speeds is an exercise in philosophy, if anything owing to grand expanses of time to think. Nonetheless, these curiosities nagged at me in flight, and they still nag at me now, so I get back in the plane and try to figure things out. It is a philosophical exercise of “what if” to contemplate how different our area would look if we changed a few dials on the weather knob. “Glaciers of the Rockies” is available on Amazon.com. Garrett Fisher is the author of seventeen books, fifteen of which relate to aerial photography. He blogs regularly about his aviation adventures at www.garrettfisher. me. The project turned into my latest book, “Glaciers of the Rockies.” In an effort to spare others a fanatical obsession to chase these glaciers down on foot or by plane, photographs of every remaining named glacier in the US Rockies are included, along with detailed maps. Given that their great distance, quantity, and difficulty prevent most people from visiting on the ground, I do strongly encourage some research, if not a grueling hike to some of the enormous glaciers remaining in the state of Wyoming. They are an undiscovered piece of majesty. W L M www.wyolifestyle.com 25
