These rare photographs, taken by Stuart Malcom Young, chronicle the 1909 Utah Arch Expedition. The grandson of LDS Church leader, Brigham Young, S.M. Young accompanied University of Utah Professor, Byron Cummings, on the historic excursion to “discover” Rainbow Bridge. At just 19 years old, Young played an important role in the expedition, chronicling the journey with photographs that would later become instrumental in building interest in the American Southwest and preserving its awesome landscapes, history, and people.
