Brown Bear & Clam

Hard to believe that I was actually out on the tidal flats at Silver Salmon Creek Lodge, Lake Clark N. P., AK for several days last month observing and photographing brown bears as they clammed during low tide (the maximum tidal range for one of the days that we were there was over 27 feet).  I had packed my 500mm lens for the trip but found I didn't really need it there at the lodge.  I was more comfortable using my 100-400mm lens either handheld or on a tripod.
