This view from the southern crater rim shows the 2030 m high point of San Miguel on the NE rim at the upper right. An ejecta-covered terrace on the eastern side of the crater is truncated by a deep inner crater. The crater morphology has varied dramatically since the beginning of documentation in the 16th century. In 1866 a 600-m-wide, 320-m-deep crater existed in the SE part of the summit crater, while a 100-m-wide, 80-m-deep adventive crater was located in its ENE part.
