Dinosaur National Monument Gallery

The first three photographs dated from the early twentieth century show the deposits, quarry, and workers from quarries at what became Dinosaur National Monument. The others are dated not long after creation of the monument in 1915. All photographs are housed at the Utah State Historical Society.
