It is not very easy to describe or visually transmit to you this huge crater
but here is an attempt anyway by way of composite pictures.

Below:  This composite photo was taken from the road leading into the crater, looking northeast. At left is the breach in the crater walls-The hill in the middle is Pondoña, the huge lava dome-To the right is the inhabited, agricultural part.

 Below: This is the breach in the crater walls, the reason why it did not become a crater lake.

 Below: This composite picture was taken on top of Pondoña, looking straight east into the flat bottom of the crater. The front ridge  of the lava dome was created by explosions in the dome.

Above: Finca Colibri is located to the back in the left hand corner, where the shadow drops down.

Above: The view which presents itself looking from our farmhouse towards west. Left is the small rocky elevation of El Chivo, the big hill in the middle is Pondoña and the tiny dome to its right is called
Pan de Azucar. These three elevations in the crater proper are extinct lava domes.
