Immediate Source of Acquisition
Purchased from Mrs. Carla S. Lansdowne, 1981.
A collection of 160 photographs (69 prints in an album and 91 loose prints) and ephemera
related to the building of O'Shaughnessy Dam, which formed the Hetch Hetchy Reservoir in
Yosemite National Park. The photographs are black-and-white snapshots that appear to have
been taken by a worker on the dam, which was completed in 1923. The album contains images of
the dam being constructed, showing equipment, a railroad, scaffolding and cranes, concrete,
and workers. The loose photographs depict the unidentified worker and family members, the
workers' cabins, fish caught in rivers, scenery in Yosemite Valley, and additional views of
the dam. Also included are clippings from 1934 about the Hetch Hetchy project and the
program for the "Dedication of O'Shaughnessy Dam, Hetch Hetchy Project, built by the city
and county of San Francisco, July 7th, 1923."
