Blue paperback 'The Wyoming Trail' with pressed flower bookmark

I found a blue paperback this afternoon around 3:15 pm in the parking lot behind Starline Coffee on Grand Ave in Jackson, Wyoming. The cover is a bright blue, the edition says 'The Wyoming Trail' in white letters, and the spine shows wear from travel. Inside, a pressed lavender wildflower sits between pages near chapter 12, and there's a little mountain doodle sketched on the inner cover. It seems this book was cherished, and I'm hoping to return it to its owner—if you recognize it, please get in touch.
