I'm curious outwitting. Did you see it stated that he was the first. I kept getting him too but actually there is a book called the first mountain man and the guy is John Colter. He was doing it long before Jedidiah Smith. Check it out and see what you think. I was a little unsure on this one because it actually could be either one. Let me know what you think?
I'll go look at this one again. Like I said I am trying to help and provide ideas. I didn't say I knew everything and that ALL my answers are correct. Helping answer these questions makes my workday go faster.
