Grizzlies can run close to 50 km per hour, I got to see a sample of that speed on the day I took this picture of the large male grizzly M122. He was getting close to two other bears, when all of sudden he sprinted away, perpendicular to the other grizzlies. Covering about 90 meters in mere seconds, this 300 kg plus boar running through shrubs, mud, and snow and over fallen trees. I'm not sure whey he ran, perhaps he saw a prey he thought he might be able to catch, within couple of minutes he was back where he started. It's one thing to read about the strength of an animal, it's a totally different experience to see that in real life in a national park.
Until nest moment,
