Witness the puzzle of huge valleys of ice that extend well below the snowline, almost to the sea. Here the ice age is still underway. While glaciers around the world are retreating, the Fox and Franz Josef glaciers still flow almost to sea level. The temperate climate at this low altitude means these glaciers are among the most convenient to visit in the world. Easy walks to the foot of the glaciers pass along ancient river valleys with steep sides bearing gigantic horizontal scars from when the glaciers have retreated and advanced over millennia. When you stand close to the foot of these glaciers, their sheer enormity is very humbling.
