An easterner, Clyde Eddy had no experience in Colorado River navigation when he brought a group of college students volunteers west to make a film on river running in 1927.  Casting off on June 27 from Green River, Utah in three Powell-style, mahogany boats, Eddy’s crew consisted of thirteen men, including Nathaniel Galloway’s son Parley, a dog named “Rags,” and a black bear cub.  Eddy was anxious to move quickly because of word that a Hollywood motion picture company planned to make a river-running film evaporated when the cameraman quit at Lee’s Ferry, but the expedition was significant because it was the first to successfully run Soap Creek rapids in Marble Canyon and the experience led Eddy to author his book, Down the World’s Most Dangerous River.

Although he returned to the river later that year to assist the Hollywood film crew, and then in 1934 to help an expedition place a plaque at Separation Rapid, Eddy returned to his job with a pharmaceutical company in New York City.
