OK, I guess its time I tell of a couple of positions I've been in.
Two of us were going to go from a lake, up a mountain for goats. It was the north side of the mountain and the bush was the usual, for north slopes, tangle of alders. I had the only rifle, my trusty 30-06 Husqavrna with good aperture sights, as the other fellow was a bow hunter. After fighting the alders for a while we came onto a trail heading up hill. A well beaten game trail. It made for great walking, but we very soon discovered it was a grizzly bear trail!
We spent some moments discussing the advisability of using the grizzly trail through the tangles, but we had been on quite a few trips together and he had faith in my shooting ability, so we agreed to carry on in the easy trail up the mountain. As a precaution, we talked a lot, but there were times when the trail was actually a tunnel and we had to hunch over to get through it! But we made it.
Another case of being close to a grizzly bear happened further north in BC, with a different hunting partner, but he too was a bow hunter, so again I had the only rifle, my same 30-06. There was an old guides horse trail up the mountain, which we were following and camped at the last little clear stream of water. We had a tiny tent which barely held our two smallish sleeping bags, with room between them for my rifle.
One evening it rained, then cleared off. In the morning we started up the trail to alpine, but in only about 50 to 75 yards came onto a big grizzly bear track, made after the rain, heading toward our tent!
Two mornings later we packed up and headed home. There had been no more rain during that time. Amazingly, about fifty yards from our camp, the same big grizzly track appeared on the trail, made shortly after the rain of two nights ago. The bear followed the trail most of the ten miles down the mountain.
To make it clear, while we had been sleeping in our tiny tent, the grizzly had come along the trail, and must have smelled our camp when he was about fifty yards or so from it. He then walked around our camp, picked up the trail again about a fifty yards on and continued on his way!
We had made no attempt to "bear proof" our camp, had bacon with us, some of which we had fried, prior to the bear coming by.
I have always wondered how close the bear came to our camp, when he went by.
