Mount Haynes el. 8,218 feet (2,505 m) is a prominent peak adjacent to the Madison River in Yellowstone National Park. The peak was named by then Yellowstone superintendent Horace Albright to honor Frank Jay Haynes (1853–1921), the first official photographer of the park. Prior to being named Mount Haynes, the peak was unofficially called Mount Burley for D. E. Burley of the Union Pacific Railroad.
