I had hiked down Sundance trail kind of late in the day, headed up canyon and passed an inviting side canyon (LUC) to the right, it had a big pool, that was where I saw her. I kept going up that canyon maybe 1/4 mile and camped. I do not recall sleeping very well that night. if at all. She was magnificent though, I got a real good look at her, she was about 100' away.
My neighbor when I lived in Telluride (not long after my experience) had a older, starving mountain lion literally attack him in Dark Canyon. He was a big guy, a weight lifter, maybe 250lbs and about 6' tall, not an ounce of fat on him. He set his pack down to rest when he spotted the starving cat across the stream, maybe 150' away. He had his pack in front of him. The cat actually charged him and he lunged forward with his pack in front to absorb the hit. The cat fell back, and so did he (I saw the claw marks on his pack!). He was lucky that there was a big stick very close, as the cat pulled back a bit and then went after him again and he wacked it hard over the head. This was not a healthy cat as I have said, a lot slower and not as strong as a healthy one. I must admit it was a hard story to believe, but I knew him well and do not doubt it happened like he said.
I have not visited Dark Canyon since. It is a scary place.
