Rocky Butte
Rocky Butte (previously known as Mowich Illahee and Wiberg Butte) is an extinct cinder cone butte in Portland, Oregon, United States. It is also part of the Boring Lava Field, a group of volcanic vents and lava flows throughout Oregon and Washington state. The volcano erupted between 285,000 and 500,000 years ago. As part of the Boring Lava Field, Rocky Butte is considered an outlier of the Cascade Range. It was produced by the subduction of the oceanic Juan de Fuca tectonic plate under the North American tectonic plate; it is the core remnant of intrusive rock from kilate Pleistocene volcano. The butte has a calc-alkaline composition and consists of basaltic andesite with olivine phenocrysts. Historically, the butte was the home of the Rocky Butte Jail, Judson Baptist College, and Hill Military Academy, as well as an extensive Works Progress Administration construction project, Portland Bible College and a campus for the City Bible Church; at the summit of Rocky Butte there is a still functioning but decommissioned rotating airway beacon. The slopes of the butte currently support Joseph Wood Hill Park and the Rocky Butte Natural Area, which includes a wide variety of flora and fauna and supports rich forest stands. Located adjacent to Interstate 205, the butte is a popular destination for hiking, climbing, and viewing mountains from its summit viewpoint.
