This is Turnagain Arm. It's saltwater, sea level, and a ceiling of fog obscured the mountain tops while the sun slipped under them to illuminate the mountain's flanks.
The photo above shows the Arm in the other direction.
This is the texture of a light snow avalanche, soft and silky. Heavy snow avalanches look more like this photo below.
And those were the totally horrendous working conditions I suffered at my office today.....
