The scent-detecting area of a grizzly bear's nose is a hundred times larger than a human's. A grizzly can zero in on the smell of food a mile away, from rotting carcasses to vulnerable young elk.

It may also have one of the most powerful senses of smell on Earth.
The scent-detecting area of a grizzly's nose is 100 times larger than a human's.
And it bristles with over a billion receptor cells...connected to over 10 million nerve cells...sending scent-powered shockwaves to the brain.
It is believed that these bears can smell other bears...trash... or even a rotting animal's carcass in the lean days of winter...from more than a mile away.
It's that super-powered nose that keeps the grizzly bear alive when a good meal is just a bit harder to come by.
Elk are an occasional meal. With young ones, just after birth, odors can be particularly strong.
It's just a matter of time before the young elk slips up.
The chase yields an important meal for this grizzly bear family...something that can be even harder to come by in the leanest days of the grizzly bear lifecycle.
Thanks to one of the strongest noses on the planet.
