This photo was taken far out on the sea ice in the Davis Straight off the coast of Baffin Island. This mother polar bear and her yearling are perched atop a huge snow covered iceberg that got "socked in" when the ocean froze over for the winter. To me, the relative "smallness" of these large creatures when compared to the immensity of the iceberg in the photo represents the precariousness of the polar bear's reliance on the sea and sea ice for its existence.
