Swiss scientists are going the low-tech route every summer to protect one of the oldest know glaciers in The Alps: The Rhone Glacier. They have laid miles of protective blankets to allow visitors to witness the incredible ancient ice from an entirely unique perspective. Continue reading for more pictures and information.
Researchers have carved a tunnel inside the glacier, large enough to walk through, allowing people to almost step back in time into a world which has not been exposed for many thousands of years. Samples of ice had previously pre-dated the glacier to at least the 17th century. But new technological advances, coupled with access to recently-exposed rock, have now allowed them to date the ancient structure to at least 11,500 years old.
