There are 6 peaks, over 10,000 feet that are carved out of glaciers. There are lakes which hold icebergs year round. However, because the earth is warming the ice masses will be gone. In the film, they showed how in the Blackfoot glacier, there was a huge collapse of ice. 25 acres were gone. Dan Fagry is an expert on glaciers. The crown of the continent is divided into two halves by the continental divide. The western half is wetter, and the eastern half is more dry. Both sides need the water from the melting glaciers. The scientists go out on an expedition. They find a lot of "rocksnot" , which is a type of algae, growing on the stream bed. This was a thick carpet, about 100 yards square. They said it was a qualitative change because of the warming water. The summers are also longer. They are worried about the fish. The bulltrout has also declined due to invasive species. It was not explained how the invasive species got there. The film showed a guy named Mark who wanted to swim in all the glacier lakes there. There was a question as to how long the glaciers would keep feeding the lakes. They thought until 2030. I would like to see them before they melt. I wonder how the animals will adapt to the changing environment. zev_jagalur https://padlet.com/zev_jagalur/vi95364ax3bl/wish/158853535 2017-03-09 02:06:00 UTC https://padlet.com/zev_jagalur/vi95364ax3bl/wish/158853535
