Manuscripts
The collection deals primarily with the professional and personal activities of Samuel Brooks Morris, a civil engineer of note in Southern California who was most active from the 1930s into the early 1960s. The collection deals with local (Pasadena and Los Angeles), state and national engineering concerns, largely related to water reclamation, dams, hydrogeology, water litigation, and a wide range of related technical publications. The material consists of a highly diverse mix of manuscripts and printed materials, including correspondence, maps, notes, charts, fliers, and brochures, often interspersed within each folder. The correspondence is primarly to and from colleagues, but also includes discusion with government officials at all levels from local to national. The collection includes a small number of photographs, located in appropriate sections of the collection by subject.

Mokelumne River, California, at Big Bar
Visual Materials
This collection contains photographs by historian Ralph P. Bieber documenting the central overland route to California as it appeared in the 1950s. Bieber visited the sites in conjunction with a project to record every aspect of the trails and circumstances associated with the migration of people to California during the Gold Rush years and subsequently. The images document the route through Missouri, Kansas, Nebraska, Wyoming, Idaho, Utah, Nevada, and California. Bieber organized and annotated the photographs himself, and his original order, based primarily on print size, has been maintained. Additionally, Bieber created photographic categories such as "Donner Party Sites," "Gold Discovery Sites," and "Sites associated with John C. Frémont." Note that Bieber did not arrange the photographs geographically.
