In Mountain Lion Territory: What to Know and Do
Mountain lions are usually quiet and elusive, living in nearly all parts of Colorado with deer and elk herds and adequate ambush cover. However, human encounters with mountain lions are on the rise, possibly due to more people moving into lion habitats, increased deer populations, expanding lion numbers, and heightened awareness thanks to technology like Ring cameras. While attacks on people are very rare, it's essential to know what to do if you encounter a mountain lion.
Encounter Tips
- Group up: Walk or hike in groups, making noise to avoid surprising a lion. Carry a sturdy walking stick and keep children close.
- Avoid approaching: Never approach a feeding mountain lion or one with kittens. Give them an escape route.
- Stay calm: Remain calm if you encounter a lion. Speak calmly, move slowly, and avoid running.
- Appear larger: Raise your arms, open your jacket, and pick up small children to make yourself appear larger.
- Defensive measures: If the lion behaves aggressively, throw objects, wave your arms, and speak firmly. Fight back if attacked. People have fought back successfully with rocks, sticks, caps or jackets, garden tools and their bare hands.
