Orion Over Mount Fairview

From the photographer: “Orion in star trails over Mount Fairview at Lake Louise, in Banff National Park, Alberta, Canada on a very clear moonlit night on February 4, 2012. This is a single long 4-minute exposure to trail the stars, taken at f/4 and ISO 100 with the Canon 5D MkII and Canon L-series 24mm lens. The location was out on the frozen lake itself.”
