Olas Grandes y EroZIHón

Like you mentioned, those rocks are underneath the sand. No doubt the sand on La Ropa was made by those rocks and a few shells. It appears that the new nearly perpendicular wall in the south corner is rebounding the waves and increasing the wave energy going along La Ropa. Just enough energy to take out the sand and leave the rocks. Just an old rock hound's opinion. I'm glad they are looking into it. I've been coming to Zihua for over 30 years and I'll be surprised if I don't think it's beautiful again this year. Have a great day.
