I love the way it shows the tender and caring aspect of a grizzly and her cub!
Looks like a small female to me, or pretty young herself may be?
In opposite to what people often believe avbout grizzlys with cubs, the female will avoid confrontations at all costs, only when forced or cornered she will risk a fight.
Much more dangerous are solitude male grizzlys, you most definately want to keep your distance from them, same counts for all bears of course, for the bears sake that is.
