I walked on glacier for 2 hours.
There were wonderful tour guides who know which way is safe.
It was amazing to be on Ice which took looooong time to grow!
The glacier is melting here.
New glacier is keep growing on the top of the mountains, and the old glacier is pushed down to lakes at the foot of mountains. Then they start melting.
So, there were many holes and small river on the glacier.
The water is drinkable!
You can hear crack and thundering sound many times from these mass of glacier.
I saw falling glacier a few times.
