A quarry exposes reddish oxidized scoria deposits with inter-bedded light-colored lava flows at Cerro la Leona cinder cone on the northern rim of Coatepeque caldera. The adjacent cones of Cerro la Leona and Cerro Cañitas on the NE caldera rim were bisected by the caldera ring faults. At least ten other basaltic scoria cones on the eastern and southern caldera rims form small hills that overlap the ring faults.
