Bursts of greenish-blue color from the Northern Lights illuminate the night sky above the Great Slave Lake in Northwest Territories. This is one of several very memorable experiences I've ever had being a photographer. I wanted to make an image of the aurora over a harsh landscape, and the Northwest Territories of Canada during winter provided me that opportunity on the night of my birthday. For this image, a friend of mine and I loaded a sled full of supplies and carried our gear out onto the frozen Great Slave Lake in an outside air temperature that was -38F with 35 mph winds. In several places we had climb over blocks and rifts of ice that resembled fault lines and little mountain ranges of their own. Conditions were so difficult that I could only keep my hand outside of my glove for a few seconds before experiencing a significant amount of pain. I was happy to discover that my Canon 5D Mark II performed beautifully in these conditions.
