15 years ago in Rocky Mountain National Park I saw a posting, on the isolated, back country, Ranger's cabin door, that a bear had been spotted in the vicinity some weeks prior. This was the same area where a bear in the past year or so attacked a man as reported on the news.
Then, for one summer in particular, I always felt uncomfortable, sometimes really uncomfortable, hiking on the western side of Rocky Mountain National Park, ALMOST EVERYWHERE. That couldn't have been a bear, I believe, with swift stealth walking 10 to 15 miles a day. That had to be mountain lion (possibly including individual offspring). Later, I saw on the news the story of a mountain lion attacking a child and killing it, in that same general area of the western side of Rocky Mountain National Park.
So, what is the difference between concern over bears and mountain lions? At REI headquarters, I heard an experienced naturalist about to retire from, I believe, the Colorado Department of Natural Wildlife, give a presentation on Colorado bear natural activities, their movements, and such. Long story, well worth hearing.
Were I to move to the mountains, I would have a very fortified house. No, bears don't own the mountains, but opening doors for these wild and natural predators, figuratively as well as literally, is reckless risk taking.
And mountain lions are a danger, too. If one loves nature, one should know predators are not lovers returning the favor. Move to the mountains, sure, and hike there, but go there with your eyes wide open.
I also once saw a bear halfway up a mountain, above tree line, near what's left of Fall River dam, grouchy, coming out of hibernation. I was completely content to quietly go my way. Later, I returned down the trail with no further incident.
Residing in the mountains, hiking and overnighting there... well, as Edward R. Murrow use to say, signing off from his legendary TV journalism program... "Good night! And good luck!"
