The following is a good review for all Alaskan scouts, and is something all the scouts visiting us should understand. Grizzly bears weight from 200 to 1200 pounds and stand 3 to 4 feet at the shoulder. Omnivorous and opportunistic, they eats lots of stuff, including great quantities of plants, fish, and even moose, caribou, deer, marmots, and ground squirrels. Black bears are much smaller, weighing from 100 to 400 pounds and stand 2 to 3 feet at the shoulder. They can appear to be the same color, although Grizzly bears have a dish shaped face, a rounded head, and a distinct shoulder hump, which black bears do not.
Bears are potentially dangerous, and highly individualistic.
Avoid B aby bears. Cubs are a bad deal, because mom likes to protect them. Sure, they are cute, but you don't want to see one. If you do, retreat from the area immediately. Avoid S mells.
