The rim of La Joya Honda maar is viewed here from the south, with the northern maar wall on the left and a cone on the SE flank on the right. The maar, whose name is sometimes spelled La Hoya Honda, is 850 x 1100 m wide and was erupted through Cretaceous limestones about 1.1 million years ago. The maar contrasts with several other Mexican maars in having a thick sequence of wet-surge deposits with primary dips up to 30 degrees.
