33. Chacaltaya Glacier, Bolivia

Once upon a time, the world’s highest lift-served ski resort was on the Chacaltaya Glacier in Bolivia. It also houses the restaurant that holds the Guinness World Record record as the world’s highest restaurant. However, if you are wanting to ski on this glacier, you’re out of luck.

It has been melting for decades, and in 2009 was reduced to only a few small patches of ice and snow near the top of the mountain. It is not only a loss of a wonderful place, but a major source of water for surrounding areas. Probably still worth checking out that restaurant though.
