Glacier National Park Fall Flashback

It was an early morning heave-ho out of bed but I ascended Going-to-the-Sun Road and reached the summit at Logan Pass just as the sun was rising. What I didn't plan on was the fog that kept washing over me in massive waves of freezing vapor. Most of the time the vistas were totally obstructed. Then, as if a plug were pulled, the fog would rapidly shift leaving gaps through which to photograph before rushing back up the steep valley walls and swamping me again.
