In August 2017, two hikers in Sequoia National Park experienced a heart-stopping encounter with a mountain lion on the High Sierra Trail. Brian McKinney and Sam Vonderheide captured the incident on video, showing the predator perched just 15 feet away. The hikers remained calm, slowly backing away without provoking the animal. This rare and terrifying encounter highlights the importance of wildlife safety awareness in national parks.
What Happened During the Sequoia National Park Mountain Lion Encounter?

The encounter between hikers and a mountain lion in Sequoia National Park unfolded as follows:
- Date: August 2017
- Location: High Sierra Trail, Sequoia National Park
- Hikers: Brian McKinney and Sam Vonderheide
- Distance: Mountain lion was approximately 15 feet away
- Duration: Several tense minutes
The hikers were backpacking when they suddenly came face-to-face with the mountain lion. They immediately stopped and began recording the encounter. The video shows the mountain lion perched on a rock, intently staring at the hikers. Following safety protocols, McKinney and Vonderheide slowly backed away without turning their backs on the animal.
After the initial encounter, the mountain lion remained in the area, lying down on the trail facing the hikers. This prompted the duo to make a crucial decision: they hiked two miles back the way they came to avoid any further confrontation with the predator.
How Common Are Mountain Lion Encounters in Sequoia National Park?

Mountain lion encounters in Sequoia National Park are relatively rare, but the animals are present throughout the park’s diverse ecosystems. Here’s what you need to know:
- Presence: Mountain lions inhabit both the foothills and higher elevations of the park.
- Sightings: Despite their presence, sightings are infrequent due to the animals’ elusive nature.
- Habitat: Areas with high deer populations (the primary prey for mountain lions) may have a higher likelihood of mountain lion presence.
- Activity patterns: Mountain lions are most active during dawn, dusk, and night, increasing the chances of encounters during these times.
It’s important to note that while mountain lions are present, attacks on humans are extremely rare. Since 1890, California has recorded only 16 verified mountain lion attacks, with six fatalities. The last documented attack in the state occurred in January 2007.
What Safety Measures Should Hikers Take to Prevent Mountain Lion Encounters?
To minimize the risk of a mountain lion encounter in Sequoia National Park, hikers should follow these essential safety guidelines:
- Hike in groups: Avoid solo hiking, biking, or jogging.
- Time your activities: Plan hikes during daylight hours, avoiding dawn, dusk, and night when mountain lions are most active.
- Supervise children: Keep a close watch on small children, as they may attract mountain lions.
- Stay alert: Be aware of your surroundings and watch for signs of mountain lion presence.
- Carry deterrents: Consider bringing bear spray or other noise-making devices.
