Without the smoke, the view from this spot would be stunning: a cerulean lake foaming with whitecaps and mountain flanks draped in alpenglow. -- "Icefields of Dreams," by Teresa Earle with photography by Fritz Mueller (Canadian Geographic, January/February 2010)
What is alpenglow? From the context, one may infer that it's the light's effect on mountain ranges. Here's the wiki explanation.
Alpenglow (from German: Alpenglühen) is an optical phenomenon. When the Sun is just below the horizon, a horizontal red glowing band can sometimes be observed on the opposite horizon. Alpenglow is easiest to observe when mountains are illuminated but can also be observed when the sky is illuminated through backscattering.
