Do you feel your community is doing enough to secure food and garbage from local bears?

As of October 2026, Wyoming remains in a period of high bear activity as animals move to lower altitudes in search of sustenance. Bears continue to frequent campsites and scavenge for food sources to prepare for upcoming winter hibernation.

Why it matters

A lack of natural food sources is driving bears toward lower elevations, increasing the likelihood of encounters with hunters and campers. This seasonal behavior is critical for bears as they attempt to accumulate sufficient weight for the winter months.

Black bears in the region are estimated to weigh approximately 200 pounds and are roughly 4 years old. Grizzly bears, such as the 700-pound specimen known as The Boss, remain active in national parks.

The players

Grizzly 610

This grizzly bear is a well-known inhabitant of the Grand Teton region observed with cubs.

The Boss

This is a massive 700-pound grizzly bear known for its size and activity in local national parks.

The details

Black bears have been documented flipping campsite equipment, including a freezer and a generator, while foraging for food. Bears are currently digging up roots and scavenging for big-game carcasses at lower altitudes.

2017 was recorded as a previous high-activity bear year.
Spring 2026 was when Grizzly 610 was spotted with two cubs.
Late September 2026 saw a black bear approach a camp in the Snowy Range.
Early October 2026 was when bear activity began to wane in Durango.
October 2026 is the current observation period for high bear activity.

Travel Outlook

This season mirrors the high-activity trends observed during the 2017 bear year. Activity is expected to remain consistent with seasonal norms until bears finalize their transition into winter hibernation.

Campers and hunters should remain vigilant and secure all food sources in bear-resistant containers to avoid attractants. Visitors to national parks should be prepared for potential closures or restrictions as bears remain active through early winter.

The takeaway

Understanding bear behavior is essential for safety during the peak foraging months before winter. Residents and visitors should prioritize proper food storage to mitigate risks when camping in bear country.
