Winds deflect an ash column originating from the summit crater of Cerro Negro in 1968.  At the same time a vent on the lower south flank, which is emitting a thin, lighter-colored steam column in this view, fed a lava flow.  The advancing flow forms the black lobe extending to the lower left corner of the photo.  The 1968 eruption began on October 23 and continued until December 15.
