In 1902, Emery and Ellsworth Kolb opened a studio in the Grand Canyon and began making photographs of mule parties, landscapes, river adventures, and nearly every other dramatic scene and incident that occurred in the area. They also successfully navigated the Green and Colorado Rivers in 1911, filming their journey. This film ran in the Kolb Studio in the Grand Canyon from 1915 until Emery's death in 1976.
