In 1981, several months after the eruption of Mount St. Helens in Skamania County, Washington, Gohlke made his first trip there to photograph the volcano and its environs. In order to convey the enormity of the event, which devastated approximately 250 square miles, Gohlke employed a variety of approaches, including aerial and panoramic views and sequential photography (rephotography) over various periods of time. From 1981 to 1990, Gohlke made five visits to the region, in many cases returning several times to the same location to record its transformation. He authored short didactic texts to accompany the images. In 2004, the Museum of Modern Art in New York mounted Mt. St. Helens: Photographs by Frank Gohlke, a solo exhibition (with accompanying catalog), co-organized by Peter Galassi, Chief Curator, Department of Photography, and John Szarkowski, Director Emeritus, Department of Photography.
