Occurred on May 13, 2021 / Salt Lake City, Utah, USA
: "I was hiking Broads Fork Trail up Big Cottonwood Canyon (a trail I've hiked frequently) when I heard noise behind me and I saw a cougar. I faced the cougar and proceeded to back up and try to make myself big and talk calmly to the cougar. The cougar periodically would sprint at me and hiss and show its teeth. She probably was about 10 feet away at her closest. The encounter lasted about 5 minutes and I have about 2 minutes of it on video. Eventually, she gave up pursuing me and I made it away safely."
