A grizzly bear crosses a river with her family in the Katmai National Park in Alaska.

Walking around in katmai National Park during the salmon run is like walking in the Zoo, just without the fences. bears everywhere! But to spot a mother with 4 cubs is a rare thing even for Katmai standards. When this mother then comes across you while you are standing on one of the two safe viewing platforms and walks only a few feet from you then this is photographic heaven.
