South Cinder Peak, the unvegetated cinder cone in the right center of the photo, is the youngest volcanic feature in the Mount Jefferson area.  A smaller cinder cone seen at the left on its south flank in this view from the SE, formed about 1000 years ago and produced a lava flow that traveled to the west.
