What makes glacier water turquoise?
Sediments or rock flour are responsible for the blue color seen on most glacial lakes. When sunlight reflects on the rock flour that is suspended on the water column, the spectacular blue color is formed on the glacial lakes, the lakes are visible from aerial photos.
What makes glacier water green?
As the melt water from a glacier starts to flow in the spring time it carries with it glacier silt or rock flour. The rock flour is very light and stays suspended in the lake water for a long time. The sunlight that reflects off these particles is what gives the lakes their spectacular turquoise blue or green colour.
Can you eat glacial ice?
Glaciers taste good, as I discovered in Norway. When it’s 85°F outside and you’ve been hiking for an hour, a big mouthful of ancient icepack tastes better than any Slurpee ever could. The diamond, sparkling ice is cold, wet, clean, and delicious–not to mention endless and all-U-can-eat.

It’s common for roadways that frequently incur black ice build up to add signage such as “Road Ices” or “Bridge Ices”.
Why is freezing fog dangerous?
When freezing fog occurs, it can cause ice buildup on roads, creating dangerous driving conditions, especially on bridges, which will freeze first because they have no ground insulation. Because freezing fog will freeze on any surface, it often builds up on power lines and can cause power outages.
Is frozen fog dangerous?
Tiny, supercooled liquid water droplets in fog can freeze instantly on exposed surfaces when surface temperatures are at or below freezing. Freezing fog can cause black ice to form on roadways. Black ice is difficult to see and so particularly dangerous.
Is freezing fog rare?
Black ice is difficult to see and very dangerous. Drive more slowly when you suspect freezing fog. It’s rare, but freezing fog can create enough ice on surfaces that it looks like an ice storm!
