I don't know the date, and you must understand my mindset when this occurred. I was NOT happy to realize there was something I never accounted for sharing the same mountain, as I was going to be there for several weeks longer. I was already aware of black bears - not much of a concern - and there were big cats - something I was always aware of. But this threw the entire equation out of kilter.
It wasn't a matter of being followed - we were just a few short switchbacks lower - living there. Suddenly, some of the previous odd sounds and movements right outside my tent all hours of the night started to make sense - and not for the better.
Oh, on occasion, they'd throw pebbles at the tent, but previously, I thought it was one of the other guys pulling pranks, although they swore it was too cold to be screwing around all hours of the night, and they though I was pulling pranks on them.
That first meeting was what in the military we'd call a "meeting engagement," but without the shooting. I was bent down behind some equipment looking at samples, and when I started back to the opposite end of the switchback - I started getting aggressively growled at by what I assumed was a big cat - but one that was sick, injured, or rabid. I just concentrated on carefully working my way past this small, tight cluster of trees on the edge of the cut it was coming from.
Only by checking behind me did I see one running at me. Now I spun to meet this threat - and adapted the same tactic I already decided to use against the cat if he came at me - rely on one, single shot in the mouth as we merged. Already decided that would be my one and only chance with just a 1911 on me. He veered and missed me be twenty to thirty feet and disappeared into that small cluster of trees. Then it went quiet - no more growling.
That was my signal to back up even faster and fog it out of there. Only when it went quiet did I realize it was another one of these critters growling at me from the cluster, and not a cat.
Maybe I didn't get jammed into a five gallon bucket as I faced him and gave him more or less, my full attention, as I still had to keep the corner of my eye on the cluster where the growling was still coming from. I didn't run, I stood my ground, and I shifted my position at the waist as he approached and then ran past me. I didn't start shooting out of fear, forcing the matter. Who knows? If I hadn't turned around and seen him - ????
Now had I started shooting - for a fact I would have hit him - without effect - and I'm confident the outcome would have been much different.
I firmly believe that if you drop one, or seriously wound one, you just declared war - especially at twilight, when they'll have the advantage for the rest of the night - and they know it.
Most think these things are animals. Not me. Not human, but not dumb animals, and I'd guess, based on scores of narratives and hundreds of site examinations, that they definitely have the capacity for revenge - and do in fact engage in the practice.
