The Canadian province of Alberta is known for its seemingly endless and pristine natural landscapes and the area surrounding Lake Louise, in Banff National Park, is no exception. Located at the foot of the Rocky Mountains, Lake Louise boasts a unique emerald colour as a result of rock flour – fine-grained, silt-sized particles of rock – carried into the lake by meltwater from nearby mountain glaciers.

Lake Louise serves as the southern gateway to the notoriously scenic Highway 93N, also known as the Icefields Parkway, which runs in a northwesterly direction towards Jasper. This road parallels the Great Continental Divide of the Americas, the separation point of watersheds draining into the Pacific Ocean from river systems flowing into the Atlantic, traversing the rugged landscape of the Rockies.

It is within the context of this vast wilderness that Pedro Restrepo, of the National Oceanic and Atmospheric Administration, snapped this stunning picture. He explains, “This photo of Lake Louise, in Canada’s Banff National Park, was taken on October 16, 2009, during a Canadian workshop on cold regions hydrology. It was taken with a Nikon D90 camera, and an 18-105 mm zoom lens set at 18 mm, and f/6.3. Exposure time was 1/160 sec and  ISO Speed 400.”

The nearby hamlet of Lake Louise, with just over 1,000 inhabitants, is the highest permanent settlement in Canada, sitting at 1,536 m above sea level.
