Today In Wyoming's History: June 2: 1899 The Wild Bunch robbed the Union Pacific Overland Flyer No. 1 near Wilcox, taking between $30,000 and $60,000. This robbery is famous in part for the large amount taken, but also for the destruction of a rail car by explosives which were used to open a safe. This is depicted in the film Butch Cassidy and the Sundance Kid. Attribution: On This Day.
Longtime Wyoming residents may wonder where on earth Wilcox is. That's because, it isn't. It's a named spot on the railroad just north of Rock River. If this same crime occured today, people would report it as having occured north of Rock River. It occured very near the junction with the Fetterman Road.
I've driven past this spot thousands of time and never realized where it was. This was a bold action, as Rock Rover was more substantial than it now is (the explosion clearly could have been heard from there) and Medicine Bow not all that far to the north.
