La Breña maar is seen here from the NE at the saddle between it and El Jagüey maar. The hill and crater at the center part of the photo are part of a cluster of nested cones formed on the floor of La Breña shortly after its formation. These post-maar eruptions produced Strombolian scoria and ash deposits due to less water being involved following the phreatomagmatic eruptions that created the maars.
