Grizzly bear (Ursus arctos horribilis) attacks resulting in human injury and known to have occurred in the national parks of North America were examined. Fifty-seven attacks in which 61 persons were injured took place in three national parks in the United States and accounted for 79 percent of the known injuries. The remaining 16 injuries occurred in four Canadian national parks. The 77 injured persons gives an injury rate of 1 person per 2 million visitors.
