To commemorate the 40th anniversary of the great eruption of Mount St. Helens in 1980, the Portland Art Museum is proud to present an exhibition that examines artists’ responses to the awesome beauty and power of the volcano. From pre-contact Native American objects to contemporary paintings, drawings, and photographs, the show will trace the mountain’s changing image and significance for local peoples. Native Americans used the substance of the volcano—mainly basalt and obsidian—to create objects of great beauty and utility. While Mount St. Helens featured in their creation stories, no depictions of the volcano in the visual arts are known before the mid-1840s, when explorers Henry James Warre and Paul Kane traveled through the area. As luck would have it, their visits coincided with the volcano’s last eruptive period and they recorded the venting of steam and ash on the north side, presaging its destruction on May 18, 1980.
