The bulk of this collection contains photographs taken on Dolph Andrus's Monumental Highway expedition and Natural Bridges Tour of 1917. There are landscape photographs of Monument Valley, Natural Bridges National Monuments, Zion National Park, Lee's Ferry, the Colorado River, and the San Juan River. Many of these photographs include Andrus's Maxwell automobile. Included are Dolph Andrus and William H. Hopkins's accounts of the journey, along with an article describing the expedition published in Good Roads Automobilist Magazine in 1918. Also included is Dolph and Irene Jones Andrus's personal history of their years in Bluff, Utah. There were three photographers involved in this collection: Dr. William H. Hopkins, O. C. Hansen, who was sent to the area by Schramm-Johnson Drug, and L. W. Clement. Dolph was involved with all three and is not always clear as to the authorship of each photo.
