Naturalist and photographer J. J. L'Heureux turned her lens on the ice and animals who call it home for her exhibit ''Penguins of the Antarctic: A Photographic Expedition.'' During multiple trips to the region, L'Heureux traveled aboard a Russian icebreaker. The route was thought to be risky, but instead of problems the expedition enjoyed perfect conditions allowing the icebreaker's captain to retrace part of Ernest Shackleton's historic journey in the early 20th century. L'Heureux enjoyed unprecedented access to Emperor penguin rookeries. Dozens of shots selected from the thousands of images L'Heureux captured make up the exhibit, including some that show small groups of penguins huddling together in the cold, others of the wobbly animals carefully making their way across the ice and snow or swimming in the freezing water.
