Humans and bears - Wild encounters

[brotherbear]

The Grizzly Bear... a few quotes from this book; from the journal of Lewis and Clark: The legs are somewhat longer than those of the black bear and the talons and tusks much longer... add to which it is a more furious animal and very remarkable for the wounds which it will bear without dying. 
"Captain Clark and one of the hunters met this evening the largest brown bear we have seen. As they fired he did not attempt to attack, but fled with a most tremendous roar; and such was his extraordinary tenacity of life that, although five balls passed through his lungs, and he had five other wounds, he swam more than half across the river to a sand bar and survived twenty minutes... his liver, lungs, and heart much larger even in proportion to his size ( than a black bear ), the heart being equal to that of a large ox; his maw ten times larger. 
Though somewhat smaller than that killed a few days ago, he was a monstrous animal and a most terrible enemy. Our man shot him through the center of the lungs, yet he had pursued him furiously for half a mile, then returned more than twice that distance, and with his talons prepared himself a bed in the earth two feet deep and five feet long; he was perfectly alive when they found him, which was at least two hours after he had received the wound. The wonderful power of life which these animals possess renders them dreadful; their very track in the mud or sand, which we have sometimes found eleven inches long and seven and one-fourth inches wide, exclusive of the talons, is alarming; and we had rather encounter two Indians than meet a single brown bear. There is no chance of killing them by a single shot unless the ball goes through the brain, and this is very difficult on account of two large muscles which cover the side of the forehead and the sharp projection of the center of the frontal bone, which isalso thick."
