Mountain lion attack of person, dog temporarily closes Solstice Canyon in Santa Monica Mountains

Solstice Canyon in the Santa Monica Mountains was temporarily closed this week after a mountain lion injured a person and tried to attack an unleashed dog, according to officials with the Santa Monica Mountains National Recreation Area.

On Tuesday, a person walking a small dog on a leash was injured when a mountain lion tried to attack the dog, officials wrote in a social media post. The person had a scratch and a puncture wound on their hand; National Park Service rangers gave medical aid at the scene. The dog wasn’t hurt. A second mountain lion was also spotted in the area during the incident.

The park was closed until 8 a.m. Thursday while park wildlife biologists assessed the situation, according to officials.

“Mountain lions are unpredictable, wild animals,” officials wrote. “While conflicts with humans are rare, there is always a risk when you are recreating in areas used by mountain lions.”

Experts recommend that if you encounter a mountain lion, make yourself as intimidating and large as possible by waving your arms, yelling and throwing objects toward the animal. Back away and allow space for the mountain lion to move away and don’t turn around and run.

The last mountain lion attack was about a year ago when the famed cougar, P-22, killed a Chihuahua on its leash after stalking a dog walker in Hollywood Hills, according to the National Park Service. The mountain lion was euthanized because of severe injuries in December 2022.
