A wide driveway leads up to an almost eerie historic structure. These 16 acres were previously the site of the city's dump, and the chimney that belonged to the incinerator remains. Now, you will find Portland's archives in the old building. Chimney Park is officially undeveloped, but the winding trail is all you need to enjoy the natural surroundings. The marshy wetlands of Smith and Bybee Lakes are adjacent to this city plot.
