Kelly Butte Natural Area
Portland, United States · built 1954
Kelly Butte Natural Area is a city park of about 23 acres (9.3 ha) in southeast Portland in the U.S. state of Oregon, just east of Interstate 205. The park is named after pioneer Clinton Kelly, who settled the area east of the Willamette River in 1848. It is part of the Boring Lava Field, an extinct Plio-Pleistocene volcanic field that contains 32 cinder cones and shield volcanoes in or near Portland. The butte contains a now-sealed concrete bunker built as a civil defense emergency operations center in 1955–56 and later used for emergency dispatching. It appears in the film A Day Called X.
