This is America at 250: Let’s Celebrate the Plurality of Our American Heritage
For the past 16 years, ASLA has collaborated with the National Park Service to host the Historic American Landscapes Survey (HALS) Challenge, a competition to document historic landscapes that tell the stories of our nation.
In ordinary times, we would be jointly promoting the 17th annual HALS Challenge, but this year, ASLA is calling on its members, students, historians, and other practitioners to submit documentation of historic landscapes in our communities.
This is an open call to complete a historical report that highlights the history, significance, and character-defining features of a selected landscape. In recognition of the 250th anniversary of the founding of United States, ASLA is encouraging reports that broadly address the theme of landscapes of liberty and freedom. All reports submitted by August 31st will be recognized at the ASLA Conference on Landscape Architecture in September.
