This photo was taken while flying in a helicopter over the Yanert Glacier near Denali National Park. We landed next to the bright blue pool shown, and walked around on top of the very rough surface (following the lead of the pilot because there are some pretty impressive bottomless crevasses all over the place) all the while marveling at the beauty and wonder of what we were experiencing. The ride was not cheap, but it was a two hour experience worth every penny. The photos I took are priceless to me.
