The Historic American Landscapes Survey (HALS) mission is to record historic landscapes in the United States and its territories through measured drawings, written histories, and large-format photography. The National Park Service oversees the daily operation of HALS. The American Society of Landscape Architects provides professional guidance and technical advice through their Historic Preservation Professional Practice Network. The Prints & Photographs Division of the Library of Congress preserves the documentation for posterity and makes it available to the general public.
Examples of HALS baseline and mitigation documentation prepared by professional landscape architectural practitioners will be shared along with examples of landscape architectural university programs using HALS to teach site documentation to students. Anyone may prepare HALS documentation for the open ended collection to promote preservation, and this presentation will explain how to prepare a HALS Short Format History for submission to the annual HALS Challenge competition.
