Glacier Bay National Park


John Muir discovered the bay in a canoe in 1879.  One hundred years earlier it was a mile thick wall of ice.


Glacier Bay was first set aside as a national monument by Calvin Coolidge in 1925.  The park is the size of Connecticut but cannot be seen by car, only by boat or plane.


It's obviously quite spectacular, even as seen from a large cruise boat.


As seen from deck 7.


Glaciers are blue because they absorb orange light and scatter blue light rays.


Purity and age also play a factor.  As the ice melts and refreezes it becomes more compact, eliminating air bubbles, so when the ice becomes more pure it absorbs more light and emits more blue.










Happy Summer Solstice to everyone in My World!

Amazing! I took this cruise too, but the weather was not cooperative we didn't get this far. Too huge icebergs couldn't get in according to the captain.

But I loved seeing your shots. Have a wonderful summer.

Interesting about the blue tint in the ice.
I love the first shot with the reflection.
