A glacier is formed by the accumulation of layers of snow. The weight of the snow then creates a dense body of ice which starts to move down the mountain side following the pull of gravity.
Glacial ice looks blue largely for the same reason that large bodies of water, either fresh or sea, look blue. Water molecules absorb light of other colours within the spectrum more effectively. The second reason is due to the lack of air bubbles in glacier ice.
Barrow is home to a strong indigenous community, the Inupiat.
The younger generation of Inupiat are torn between the traditional way of their people and the modern world presented to them from not only the lower 49 states but also the middle and southern part of Alaska itself.
Whaling is a big part of Inupiat culture and I find myself conflicted in the matter. The animal conservationist in me believes that whales should not be hunted but I also respect their ancient way of life and the importance of not letting it slip away completely. I take some comfort from the fact that the number of bowhead whales that can be hunted each year is restricted and closely monitored.
We crossed the Bruvegen on a cold and blustery evening to get to the cable car to Fjellheisen. We passed the Arctic Cathedral on the way. It looked particularly majestic shrouded in blue at this time of the night.
