The SE wall of Cráter Elegante reveals a cross-section of a scoria cone that existed prior to explosive formation of the maar. The light-gray remnants of the sill intrusions are visible at the low point of the cone and below its right flank. The vent was located where the SE part of Cráter Elegante is now. The surface of the cone is mantled by pyroclastic surge deposits from the maar-forming eruption.
