In the meantime the hunters had accumulated nearly half a ton of dried meat, buffalo being plenty. The grizzly bear, however, was also present, active, aggressive, and dangerous as usual. They infested the camp at night, causing much alarm, and once carried off buffalo-meat from a pole within thirty yards of the men. A hunter sent out to bring in meat was boldly attacked by a bear and narrowly escaped death, being pursued to within forty paces of the camp. Another animal was killed when rushing up to attack men who had to climb a tree, while making sufficient noise to attract their rescuer, Drewyer, the interpreter and hunter, who shot him through the head. He proved to be the largest they had seen, being eight feet seven and a half inches long, while his fore feet measured nine inches and hind feet seven inches across, and eleven and three-quarters long exclusive of the talons. Another hunter was attacked by a grizzly, fortunately near the river, so that he was able to conceal himself under a steep bank; otherwise he would probably have lost his life. The perils of navigation and the chase were not all, for a cloud-burst and hail-storm contributed to their danger and suffering. The hail was so large and driven so furiously by the high wind that it knocked down several of the men, one three times, bruising another very badly and wounding some so that they bled freely. The fallen hail lay in drifts, which in places completely covered the ground, and some of the stones weighed three ounces and measured seven inches in circumference. Clark, Chaboneau and his wife took shelter under shelving rocks in a deep ravine, congratulating themselves on their protected position. Suddenly, however, the rain fell in a solid mass, and instantly collecting in the ravine, came rolling down in a dreadful torrent, carrying rocks and everything before it. "But for Lieut. Clark, Chaboneau, his wife and child would have been lost. So instantly was the rise of the water, that as Lieut. Clark had reached his gun and began to ascend the bank, the water was up to his waist, and he could scarce get up faster than it rose, till it reached the height of fifteen feet, with a furious current which, had they waited a moment longer, would have swept them into the river just above the Great Falls, down which they must have inevitably been precipitated."
