Actually, it all happened really fast. The wolf came running at a fast pace. I was kneeling/sitting in a couple inches of water shooting all the images I could before it was over.
He moved pretty fast and it was all I could do to keep him in frame.. As he approached, he was too close for my 500mm to focus..
Eventually, he turned his interests to fishing and spend several minutes fishing with a large grizzly.
I think I have several hundred images from the interaction.. it was awesome being so far in the back country watching two of my favorite animals just a few feet apart trying to catch fish..
