Prominent flow levees are visible on the surface of the 1968 lava flow from Cerro Negro in the foreground, marking individual flow lobes. This flow originated from a spatter cone (named Cristo Rey) on the south flank of Cerro Negro and traveled 1.5 km from the vent. Tephra covers and smooths the surface texture of an older flow in front of the cone to the left; this flow was emplaced during the 1960 eruption.
