The Carl Hoffmeyer Scrapbook on Operation Deep Freeze I, dated 1955-1957, contains newspaper clippings about the United States’ exploration and research progress during Operation Deep Freeze I. Newspaper clippings about the exploration of Antarctica by the United Kingdom, Russia, New Zealand, and Japan are also included in the scrapbook. Hoffmeyer divided the scrapbook into several sections; the sections are divided by articles that define the purpose of Operation Deep Freeze, the equipment used during the expedition, and the operation’s progress.
