These two historic markers are located at Como Bluffs, between Rock River and Medicine Bow Wyoming. I'm sure I've stopped at them before, but it's probably been over thirty years and I've never photographed the markers before, or if I did it would have been that long ago.
The first marker is for the fossil fields nearby. The sign tells the story. I'd only note as an aside that my father told me that back in the 1940s he stopped at the fossil cabin with his father and the owner of hit gave him a fossilized dinosaur egg from the nearby fossil beds. Unfortunately, it's long since been lost.
The train robberies sign also speaks for itself. The first robbery noted is a famous one by The Whole In The Wall Gang, famously depicted in the film Butch Cassidy and The Sundance Kid. The other details the life of Bill Carlisle, the "Gentleman Bandit".
Structures at this site are depicted in these two photographs, including the famous "fossil cabin". A nearby sign notes that it was featured in "Ripley's Believe It Or Not".
