Ten Who Dared is a 1960 American Western film directed by William Beaudine and starring Brian Keith, Ben Johnson, John Beal and James Drury. It was produced by Walt Disney Productions and released by Buena Vista Distribution. It tells the story of United States Army officer John Wesley Powell, who was the first to travel down the Colorado River, and the dangers that he and nine other men had to face while making a map of the region during their 1869 expedition. Hired by Walt Disney Studios in 1959 as a technical adviser, Otis R. Marston led a film crew through the Grand Canyon to film river running and background scenes for the film.

The film is set in the United States, in 1869.

Thanks to the activity of explorers, soldiers and trappers, the American territory is now well known. On the cards, there are few places marked with an explicit Unexplored (unexplored). One of these places shrouded in mystery and avoided because they are believed to be full of danger is the Colorado River.

John Wesley Powell, a former Northern major of enormous scientific culture, but without an arm, lost at the Battle of Shiloh during the Civil War, gathers 9 men, including his brother Walter, marked by the sufferings of Southern captivity, and obtains 4 boats to set out to discover Colorado.

The journey is long and difficult. On the way, a boat is destroyed by the whiskey drunk occupants.

The meeting with Baker, trapper husband of an Indian and friend of Powell, who tells of terrible waterfalls, makes one of the men abandon the company. Three others mutiny, continuing the journey overland alone, but are killed by the Indians who pass them off as the killers of a squaw.

Powell eventually finds the point where the Colorado flows into Lake Mead, concluding the great feat with success.

Besides the Grand Canyon, other parts of the film were shot at the Big Bend of the Colorado River, Professor Valley, Arches, Dead Horse Point, Dewey, Castle Valley, and Westwater Canyon in Utah.
