Two bear attacks last week in Glacier and Yellowstone National Parks have left one man dead and two others injured.

According to information from Glacier officials, the body of a missing hiker was  recovered and identified as Anthony Pollio, a 33-year-old man from Davie, Florida. Pollio’s body was discovered by search and rescue crews at approximately 12 p.m. on Wednesday, May 6, in Glacier National Park. 

Officials have yet to say if a grizzly or black bear was involved.

Sunday, May 3, Pollio communicated plans to hike the Mt. Brown Trail toward the Mt. Brown Fire Lookout. Park officials were notified of Pollio’s disappearance on Monday afternoon and initiated search and rescue operations.   

Search and rescue teams located some of Pollio’s personal items along the Mt. Brown Trail approximately 2.5 miles from the trailhead, which prompted a focused search of the surrounding area. 

Pollio was discovered deceased approximately 50 feet off the trail in a densely wooded area with injuries consistent with a bear encounter. 

According to a story on people.com, Pollio’s father said he believed his son may have used bear spray. 

The last human fatality caused by a bear in Glacier occurred in 1998 in the Two Medicine Valley. The last time a bear injured a human was in August 2025.  

The sequence of events leading to the bear encounter remains under investigation; however, evidence suggests that this was a surprise encounter.   

The section of trail where the incident occurred has been temporarily closed while the investigation continues. Park staff are working to determine next steps based on field assessments and wildlife behavior monitoring. 

Visitors are reminded to stay off closed trails. According to park officials, several trails in the area are closed due to bear activity.

They include Snyder Ridge, Sperry Trail (Crystal Ford) to Lincoln Lake Trail, Sperry (Gunsight Pass); Lake McDonald Lodge - Sperry Chalet,  Mt. Brown Lookout; Sperry Trail - Mt. Brown Lookout,  Sperry (Gunsight Pass); Lake McDonald Lodge - Sperry Chalet, Lincoln Lake; Going-to-the-Sun Road - Lincoln Lake; Snyder Lake, Sperry Trail to Snyder Lake; Fish Lake (Snyder Ridge); Sperry Trail (Crystal Ford) to Fish Lake; Gunsight Pass; Lincoln Lake, Going-to-the-Sun Road - Lincoln Lake.

Two areas are posted for bear frequenting, but are not closed. They include Apgar Bike Path, Apgar Bike Path from Headquarters to Apgar Village and Avalanche Lake, Avalanche Campground - Foot of Avalanche Lake.

In the Yellowstone attack, officials said on the afternoon of May 4, two hikers were injured by one or more bears on the Mystic Falls Trail near Old Faithful in Yellowstone National Park.

Emergency responders, including law enforcement, EMS personnel and interagency partners, responded to the scene and provided aid before transporting two male hikers, ages 15 and 28, from the area by helicopter. 

Based on evidence collected so far, park staff believe a female grizzly bear with two or three cubs-of-the-year (cubs in their first year of life) were involved in the encounter. This incident remains under investigation

It’s the first incident of a bear injuring a person in Yellowstone in 2026. The last time a visitor was injured by a bear in the park was in September 2025. The last human fatality caused by a bear occurred in 2015 in the Lake Village area of the park.

Temporary trail, backcountry campsite, and fishing closures remain in effect northwest of the Old Faithful area following a bear incident earlier this week.
