Crystal Pool, Glen Echo Park located in the suburban community of Glen Echo just outside of Washington, DC. In its prime, Glen Echo Park had a variety of attractions, including bumper cars, shooting galleries, a roller coaster and the Crystal Pool, a large pool, the remains of which can be seen to this day. After a series of protests in the 1960s, Glen Echo Park was opened up to members of all ethnic groups. The influx of urban African Americans caused the surrounding community to complain, and in 1968, Glen Echo Park was forced to shut down, and was turned into a national park in 1977. The National Park Service collaborated with artists and arts organizations to create a rich arts program in the spirit of the original Chautauqua movement. Today the programs and facilities at the Park are managed by a nonprofit organization, the Glen Echo Park Partnership for Arts and Culture, Inc., while the National Park Service continues its role in managing the grounds and providing historic interpretation.
