Hi y'all, I've just started up on the road and I was looking for any suggestions for cheap/free pdf guides to foraging in:

Colorado rocky mountains (southish West) Utah Idaho Oregon (at elevation and sea level) Red woods

I'm doing mostly dispersed camping and hiking so I haven't had much connection to look things up as I go. I have a good sense of the usual edibles but I'm very curious beyond just edibles, and id like to be aware of look alikes

If you have a Dropbox download of any books you're willing to share for free or I can send a very small amount (like around ~$7, I've got a limited budget being on the road) I would be so grateful!

Thanks!
