Photo taken on July 7, 2011 shows tourists ride on a road near the Athabasca Glacier in the Canadian Rockies, Alberta, Canada. The road was totally covered by the Athabasca Glacier 100 years ago. As the Athabasca Glacier keeps on melting 2 to 3 meters a year, the size of it now has been dwindled more than a half in comparison with it 125 years ago.
