Beside not being the clearest photo it is interesting because it captures the meting of a mother grizzly with three cubs and a sub-adult male grizzly bear.
Coming from opposite directions it was the young male that was most surprised as the wind was at it’s back and he was not able to smell the mother. The mother had picked up on the males scent earlier and was not concerned. It was the male that retreated to the upper beach and walk around the family before moving along the beach. Most grizzlies go out of their way to avoid a mother with cubs.
