Howdy Akrisoner, it's been a spell. Unless you have been around bears as much as I have it can be difficult to tell the difference. The way I put it is if you see a black bear, you're not sure if it is a grizzly or a black bear, if you see a grizzly you know it is a grizzly and not a black bear. My wife and I, especially myself have spent decades studying bears especially grizzlies. I was very fortunate to have worked along side bear biologists to tag and weigh etc. grizzlies from helicopter. This is actually a fairly big bear and lacks the very distinctive shoulder hump that grizzlies have even at a young age. It gives them incredibly powerful shoulders and front legs . A grizzly does not have the tall rounded ears of the black bear and also the grizzly has a concave face from it's eyes to the tip of it's nose where as a black bear has a relatively straight face from it's forehead to the tip of it's nose. Colors can vary widely for both bears. Even grizzlies can be from their typical brown color to several different shades of brown to black and white and one never knows where you may come across one, they certainly are not restricted to the mountains. A few years ago a fellow was killed by a grizzly an hours drive north west from the house here, west of Airdrie, and I have seen grizzlies near Hinton. Here's a picture for comparison. I must say I envy your cousin living near Hinton. Beautiful country, that's where I should be living with my outdoor photography and other activities.
