The internal structure of a cinder cone can be seen in the southeastern walls of Crater Elegante. Lynch (1981) named this Gutmann's Cone and reported its age to be about 433 thousand years, or much older than the crater. The vent of the cone was centered near the middle of this view and at the bottom of the talus slope. At the extreme left edge of this picture is the side of a dike of basalt that was emplaced in the cinders above the top of the lava flows that form the lower cliff. This dike was injected horizontally outward from the vent of the cone. The dike is shown in the next image.
