A hiker was killed today in northern Colorado in a suspected mountain lion attack. It is a rare and sobering moment for anyone who loves the trail. If officials confirm it, this would be the state’s first deadly mountain lion encounter since 1999. For hikers, runners, and dog walkers, this is breaking news that changes how we plan and move outside, starting now.
What happened on the trail
Authorities say the victim was a woman hiking in foothill country, where people and wildlife often share the same ridges and draws. The scene is now closed as officers and biologists collect evidence. The goal is simple, confirm whether a mountain lion was responsible. That work is careful and slow, and it matters. It tells us what to do next.
How investigators confirm a lion attack
Investigators look for clear signs. Tracks with large pads and no claw marks. Bite and scratch patterns that match a powerful cat. Sometimes they find a cached site, where a lion has dragged and covered a kill with leaves or soil. They also use lab tools. DNA swabs can match hair or saliva to a specific animal. A necropsy, an animal autopsy, may follow if a lion is located. This is the process that separates rumor from fact, and it protects both people and wildlife.

The reality for hikers, rare but real
Fatal mountain lion attacks are very rare. That is why this incident stands out. Still, rare is not never. Anyone who hikes in the West shares space with big predators. We enter their home. Our job is to be seen, heard, and ready. Most encounters end with a cat slipping away. When they do not, preparation can make the difference.
Keep children and pets close, within arm’s reach in lion country. Small, fast movement can trigger a chase.
Smart steps if you meet a mountain lion
Staying calm is hard, and it is essential. Think of the next steps as a simple checklist you can practice before you need it.
- Stop, stand tall, and make yourself look big. Raise your arms, open your jacket, and hold your ground.
- Speak firmly. Do not scream, do not run, and do not turn your back. Running can trigger pursuit.
- Gather your group. Bring kids beside you. Pick up small dogs, if you can do it safely.
- Back away slowly while staying face to face. Give the animal a clear escape route.
- If it acts aggressively or attacks, fight back with everything. Aim for the face and eyes, use rocks, sticks, or your pack.
If a lion attacks, you fight. People have stopped attacks by targeting the eyes and nose and using whatever is in hand.

Pack like a pro, hike like a neighbor
Prepared hikers move with purpose, not fear. Start with daylight hours, and avoid solo dusk or dawn outings when lions are most active. Make noise on blind corners. Scan ahead for spoor, paw prints in soft dirt, fresh scat, or a cached site. If you see one, leave the area calmly. Do not approach for photos.
What you carry matters too. It should be light, simple, and always within reach.
- A loud whistle, charged phone, and headlamp
- A small first aid kit and extra water
- A trekking pole or two, useful for balance and as a deterrent
- A leash for dogs, clip it before you hit brushy sections
Practice with your gear at home. Open your jacket wide, lift your pack, blow your whistle, and rehearse your firm voice. Muscle memory beats panic.
Community on the trail, respect in the hills
Today’s loss is heavy. The right response is not to hide indoors. It is to hike smarter together. Choose marked routes. Share your plan and return time. Check local advisories before you go, then check in after. If you see a lion, report it to park staff. Your call helps others avoid a surprise.
Mountain lions belong to these hills. So do we. Coexistence is not a slogan, it is a set of actions we take every time we lace up. We move with partners. We keep pets close. We stay present, eyes up, and ears open. We pack a little knowledge, then we carry it with care.
Conclusion
One woman’s life ended on a trail that many of us love. Honor her by stepping into your next hike with calm focus. Respect the place. Prepare for the rare. Then go, enjoy the crisp air, the open view, and the quiet strength of the mountains. Your best day outside is still ahead, and it starts with how you start today.
