Avalanche

One thing I have noticed about Antarctica is that it is always surprising, but it is not usually startling. Every day something unexpected happens, but not usually in a hurry. On the day we walked to the end of Lake Hoare over towards the Suess Glacier, it was very still. We heard the crunching of our own footsteps and then quiet. Then we heard a distant rumble and noticed a cloud of snow coming from the ice falls on the Suess. It was far away, but still very distinct. We heard this happen several times and the snow cloud became more dense and started to slowly drift towards us.
It's hard to imagine what quiet sounds like. In our modern world at home in cities we have people, construction, traffic, and music playing in public spaces. Even in the wild there are insects buzzing and the sounds of the wind blowing through the trees. I have never experienced quiet like the quiet of the polar regions on a calm day.
