Los Elotes island with a normal fault
Volcanoclastics,   Here's a lava flow in a channel carved into the ash flow tuff.
Kayaking here at Espiritu Santu island
Sand is totally Biogenic..... Only sea shells and coral, not reef-forming hard coral
There is granite on the East side of the island and then it gets to this fault and suddenly you get into the volcanic rocks
Those are all frigatebirds
