I'm trying to find what this piece is called

For that series of documentaries on the Rocky Mountains and the upcoming one about Teddy Roosevelt, they had this music playing during the commercials that’s a nice, soaring symphonic bit. I was wondering if any among you who have seen these know what that piece is called and who it’s by.

Thanks

I haven’t seen it but there are a few big time Americana musicians and I can’t imagine that they would pass something like that up. Again, I haven’t seen it, but I would guess A. Copeland’s Appalachian Springs.
