A radial fissure on the NE flank of Volcán Wolf has produced extensive lava flows that in part lap onto the flanks of the main shield volcano.  A sharp break in slope separates the low-angle flank rift zone, whose smooth profile is interrupted by a few small cinder cones, from the upper shield volcano, which has some of the steepest slopes of Galápagos shield volcanoes.  A fresh unvegetated lava flow from the main shield at the extreme left was deflected to the south by the lava produced from the NE rift. Photo by Lee Siebert, 1978 (Smithsonian Institution).
