A blocky andesitic lava flow, its margins marked by prominent flow levees, descends the SW flank of Trident volcano in Katmai National Park, Alaska. The lava flow, seen here from the WSW in 1978, was part of a series of eruptions from 1953 to 1968 that constructed the snow-covered cone in the background. The lava flows diverge around the lighter-colored surface of an older lava dome at the right center.
