Subduction of the Juan de Fuca Plate under the North American Plate, causing volcanism in the Boring Lava Field
Subduction of the Juan de Fuca Plate under the North American Plate, causing volcanism in the Boring Lava Field

The Boring Lava Field is a Plio-Pleistocene volcanic field with cinder cones, small shield volcanoes, and lava flows in the northern Willamette Valley of the U.S. state of Oregon and adjacent southwest Washington state. The zone became active about 2.7 million years ago, with long periods of eruptive activity interspersed with quiescence. Its last eruptions took place about 57,000 years ago; individual volcanic vents are considered extinct, but the field itself is not. The volcanic field covers an area of about 1,500 square miles (3,900 km2) and has a total volume of 2.4 cubic miles (10 km3). The highest elevation of the field is at Larch Mountain, which reaches a height of 4,055 feet (1,236 m). The Portland metropolitan area, including suburbs, is one of the few places in the continental United States to have extinct volcanoes within a city's limits. The probability of future eruptions affecting the Portland metropolitan area is very low. (Full article...)

Richard Gerstl

Richard Gerstl (1883–1908) was an Austrian painter and draughtsman known for his expressive and psychologically insightful portraits, his lack of critical acclaim during his lifetime, and his affair with the composer Arnold Schoenberg's wife. At the Academy of Fine Arts Vienna, Gerstl studied under the notoriously opinionated and difficult Christian Griepenkerl. He began to reject the style of the Vienna Secession and what he felt was "pretentious" art. For the summers of 1900 and 1901, Gerstl studied under the guidance of Simon Hollósy in Nagybánya. Inspired by the more liberal leanings of Heinrich Lefler, Gerstl once again attempted formal education. His refusal to participate in a procession in honor of Emperor Franz Joseph I of Austria further ostracized him and led to his departure; he felt that taking part in such an event was "unworthy of an artist". Gerstl painted this oil-on-canvas laughing self-portrait in an Expressionist style in the year of his death by suicide. The painting is now housed in the Österreichische Galerie Belvedere in Vienna.
