The "White-Masked Bandit" robbed trains for pocket change and was dubbed the "Robin Hood of the Rails." After a robbery near Rock Springs netted him just $52.35, Carlisle was arrested, escaped, recaptured, and ultimately pardoned. He later turned his outlaw fame into a business empire and speaking career. One of the last of his kind.

Scout. Soldier. Detective. Assassin? Horn worked as a hired gun after losing his own ranch to rustlers. Suspected of killing 17 people, including Matt Rash and Isom Dart, Horn was finally convicted for the murder of a 14-year-old boy—a crime he may not have committed. He was hanged the day before his 43rd birthday. His guilt is still debated today.

Josie and her sister Ann were raised in Browns Park, where they rubbed elbows—and more—with outlaws like Butch Cassidy. Josie was one of only five women allowed at Robbers Roost and spent her life ranching, hunting illegally during the Depression, and bootlegging in Prohibition. She claimed Butch visited her after Bolivia. She passed away at 90, tough as ever.

Calamity Jane announced her arrival in Rock Springs by emptying her six-shooter up North Front Street and cussing like a sailor. She lived in a dugout along M Street and spent most of her time at Uncle George Harris’ Bar on J Street. Famous for her sharp-shooting, rowdy behavior, and disregard for societal norms, Jane remains one of the West’s most colorful—and controversial—characters.

Matt Rash was a Browns Park rancher, engaged to Ann Bassett, and friend of Isom Dart. After receiving anonymous threats to leave town, Rash was gunned down—many believe by Tom Horn, working under the alias “Tom Hicks.” Rash’s murder marked the beginning of a deadly wave targeting independent ranchers in the area.

Ann Bassett earned her “Queen” nickname by taking on powerful cattle barons—and winning. With the Wild Bunch’s help, she defended her family ranch and became a symbol of frontier resistance. Arrested at 25 for rustling, she was acquitted and went on to live a full life on the range. She was also romantically linked to Butch Cassidy for nearly a decade.

Isom Dart was a Black cowboy respected for his skills and character—despite his reputation as a “cattle liberator.” Once arrested and hauled to Rock Springs, Dart saved the injured sheriff after their wagon overturned. The sheriff was so impressed he testified on Dart’s behalf, leading to his acquittal. Sadly, Dart was later ambushed and killed, likely by hired gun Tom Horn.

The legendary leader of the Wild Bunch got his nickname right here in Rock Springs. After his first major bank robbery in Telluride, Colorado, Parker hid out in town working in a butcher shop under the name “George Cassidy.” Locals started calling him “Butch”—a name that stuck. Known for his charm and loyalty to friends, Butch would go on to rob trains and banks across the West. Some say he died in Bolivia… others say he returned to Browns Park and visited old friends.
