In 1906 Teddy Roosevelt gave initial protection to the Grand Canyon when it was designated a National Monument. In 1919 it bcaame a National Park due in no small part to photographers Emery and Elsworth Kolb. They scoured the back country looking for the perfect photos to entice people to come and visit. Here are three examples showing their efforts taken in 1911, 13 and 15. They were not only intrepid explorers and photographers, they were also not above instilling a little humor in their pictures. Case in point is this 1910 photo showing two tourists working their way back up Bright Angel Trail (click to enlarge).
