Large angular clasts in an oxidized scoria matrix of the Acajutla debris-avalanche deposit are exposed at the Pacific Ocean coastline more than 40 km from Santa Ana volcano.  Clasts with a jigsaw fracture pattern can be seen at the top of the photo.  Large clasts to 6 m in exposed dimension occur nearby.  Note the rock hammer in the center for scale.
