Lake Louise is a popular tourist hot spot within the Banff National Park in Alberta, Canada. The region experiences subarctic climate, with average annual snow fall of 3.3m (11ft) and minimum temperature below -50C (-59F). Even in early April, the lake surface is normally still frozen, providing a short cut to the mountains for the hikers, as well as an ice surface for skating and other winter sports activities.
This beautiful Rocky Mountain landscape was sculpted by ice-age glaciers beginning about two million years ago. The glaciers carved these mountains and gouged the valley into a deep basin which was once filled by the Victoria Glacier. About 10,000 years ago, the ice glacier retreated and left behind a pile of rocks that dammed Lake Louise.
