A unique, local phenomena that is affectionately called the 'BBC', or Bridger Bowl Cloud, which descends like a blanket over the east-central Bridger Mountains and leaves behind a prodigious amount of snow. In reality, the abundance of snow is not necessarily caused by a cloud, but rather a weather event called 'upslope precipitation', wherein the snow starts to fall when a cold, moist northwestern air flow moves through the canyon and is forced upward by the unique geography of the mountains, creating precipitation in the higher elevations, as seen here near Bozeman, Montana, US.
