ALASKA - UNDATED: Brown Coastal Bear charges powerfully across the river in Bristol Bay in an attepmt to catch a salmon in Alaska. Bravely staring down a bounding 600 pound bear, photographer Charles Glatzer captures one of natures most impressive sights. Snapping the image on the banks of a salmon filled river in Bristol Bay, Alaska, during the annual autumn bear feeding frenzy, Charles was standing just feet away. Observing the lone male for half an hour as it attempted to pounce on fish to feed on for its winter hibernation, Charles, 53, caught the bear in perfect flight. Once the bear had finally poached its fish supper, it chomped down, preparing itself to roam the river again for another all important meal.
