Twin Rocks Friends Conference is located in Rockaway Beach, Oregon, serving as a summer camp and conference site for both Friends (Quaker) constituency and other organizational events. Discussions for the Summer Conference program began in 1916 from joint concerns of the Oregon Yearly Meeting of Friends and the Christian Endeavor youth organization in an effort to provide vacations and spiritual development for youth. The first session in 1918 at the present site was so successful that a Committee of Arrangements was formed for future events. Today the site is managed by Twin Rocks Friends Conference Board.
Included in the collection are annual reports, financial records, minutes, publications, newsletters, promotional materials, calendars, schedules, legal documents, audio visual materials in the form of audio cassettes, 16 mm films, slides, and photographs. Subjects of these materials center around the various camping programs offered at the site from boys' and girls' summer camps to adult retreats and corporate functions. There are records of several directors and the presiding board, including developmental reports and outreach materials. Several years of the Twin Rocks Sandpiper newsletters are also included as well as plats of the grounds and some architectural drawings of various buildings. Copies of a 1925 published songbook titled Twin Rocks Summer Camp Songs in the collection are in fragile, but usable condition.
