the grizzly is a large, powerful bear standing about six feet tall and weighing approximately eight hundred pounds. due to the bears impressive size and intimidating strength, many early settlers who explored the american west documented their encounters with the bear. when lewis and clark were traveling to the pacific in 1805, for example, lewis recorded how grizzlies surrounded their camp in montana. as settlers continued to push westward, grizzlies were hunted and pushed out. therefore, the majority of grizzlies in the american west have disappeared. some wildlife experts are concerned about the small number of grizzlies in north america.
