I have lived in the deep back woods for whole seasons. Not as well traveled as you, But I have been all over this particular part of MT...
Although I don’t hunt bear, I hunt in bear country and am familiar with bear bones. They do die, after all.
I didn't say they aren't there - just very rare. A viable Sasquatch population is likely to be far smaller than the bear population - even smaller than Griz alone among the bear pop. Therefore, just by the statistics, finding Sasquatch remains would be infinitely less likely... And finding bear or wolf, or even moose is not something that happens often at all.
Believe what you want - I don't need to be convinced. I had my own episode 4 days back in the Bob Marshall Wilderness, and have also cut sign on more than one occasion. I know they are there.
I know someone who had an incedent and won’t talk about it. He said he knows what he experienced and leaves it at that.
