How to Avoid Grizzly Bears While Hiking in Yellowstone

For individuals planning to hike in Yellowstone, it’s crucial to adopt best practices for bear encounters. These practices include understanding bear behavior, recognizing signs of their presence, and carrying bear spray. Park authorities strongly emphasize the importance of implementing these precautions.

Over the years, grizzly bear-inflicted injuries have exhibited fluctuations in different park areas. In developed areas, the average number of injuries during the 1930s to the 1950s was approximately one per year. This increased to four per year during the 1960s but declined significantly to one injury every two years (0.5/year) in the 1970s. Since 1980, there have been only two grizzly bear-caused injuries in developed areas, averaging approximately one incident every 20 years. In the backcountry, 34 reported injuries were caused by grizzly bears, averaging one per year.

How Many People Are Killed by Grizzlies in Yellowstone?

While bear-inflicted fatalities in Yellowstone capture public attention, it’s important to contextualize them within the broader spectrum of park-related incidents. Since the establishment of Yellowstone in 1872, eight fatalities have been attributed to bear encounters. Comparatively, more individuals have lost their lives due to drowning incidents (125 incidents) and burns from falling into hot springs (23 incidents). The probability of being killed by a bear (8 incidents) is slightly higher than the chances of being killed by a falling tree (7 incidents), in an avalanche (6 incidents), or being struck by lightning (5 incidents).

Unsubstantiated Grizzly Bear Incident

Legend has it that in 1907, a man prodded a female grizzly bear’s cub with an umbrella, leading to a retaliatory attack. However, the authenticity of this incident remains in question, as it is not mentioned in official park reports or local newspapers from 1907. The anecdote is derived from the book “Book of a Hundred Bears” published in 1909 by F.D. Smith, which includes numerous stories lacking supporting documentation.
