A steam plume rises from the summit of Pavlof volcano, whose upper slopes are snow-free as a result of its frequent eruptions. More-extensive glacial dissection of Pavlof Sister volcano (upper right) has produced a series of parasol-ribbed ridges that radiate from the summit. Only one historical eruption is known from Pavlof Sister.
