Overview
- Hikers on the Crosier Mountain Trail near Glen Haven found an adult woman unresponsive and drove a nearby lion away by throwing rocks, with a physician in the group finding no pulse.
- Colorado Parks and Wildlife coordinated ground and aerial teams and euthanized two mountain lions in the area in line with agency public-safety policy.
- Investigators report evidence consistent with a mountain lion attack, but it remains unclear whether one or multiple animals were involved.
- The Larimer County coroner will release the woman’s identity and official cause of death, and authorities say she was likely hiking alone.
- If confirmed, this would be Colorado’s first fatal mountain lion attack since 1999, and nearby trailheads were temporarily closed as officials reiterated safety guidance for hikers.
