speaking of buffalo hunters,
Billy Dixon's biography book written by his wife, and iterated by him, "Life and Adventures of Billy Dixon"
http://www.gutenberg.org/ebooks/45075is quite good at giving a visceral depiction of the adventure, risk, gore, and lucrative money made hunting buffalo.
it's free via gutenberg on Kobo and I'm sure other e-books. I also have a hard-copy published by the Panhandle Plains Historical Musuem,
http://www.panhandleplains.org/pages/home.asp, during my trek to Adobe Walls.
I wish I could share the pictures I found. Right now I'm having issues transferring them to the PC. Worst case scenario I can just take pictures of the pictures with my phone. But that museum is a gold mine for this kind of thing. I spent a good two days there. The weapons they have shared there is absolutely stunning. I can only say I'm honored I was able to help restore and preserve some of their artifacts.
