This series consists of approximately 840 photographs depicting a diverse array of subjects, mainly focused on the Western way of life, including landscapes, ranch scenes, wildlife, cattle drives, rodeos, and photographs of Rollins or his wife traveling through the West. There is a large collection of original postcards (approximately 290) produced by the Pendleton Drug Company to celebrate the Pendleton (Oregon) Round Up circa 1922. They include images by Oregon and other Western photographers such as R.R. Doubleday, J.E. Stimson, W.S. Bowman, and Major Lee Moorhouse. There is one photograph album dedicated to gold prospecting and mining; photographs are on a variety of mounts, including board, and vary in size. This series is organized loosely by subject of the photographs. Box 16 contains twelve canisters and boxes of home movies, variously titled "Beaver," "Moose," etc. Box 23 contains Rollins' photographs taken as part of the Princeton Scientific Expedition of 1889.
