Semisopochnoi volcano, November 2012. Oblique aerial photograph courtesy of Roger Clifford. Semisopochnoi consists of a large caldera (about 8 km or 5 miles across) and a number of significant post-caldera composite cones. In this photo, the three closely-spaced snow dappled cones in the middle form the Cerberus complex. The large cone at lower right is called Sugarloaf.
