Large collapse on the northeast flank of the volcano (El Ventorrillo peak), these are the remnants of an old volcano called Nexpayantla which was destroyed in a Bezymianny/Mount St. Helents style eruption!

Amazing layering of the pumice rocks that came out during different eruptive episodes, I love the different colors

Nice crew! Everytime we were riding up to the volcano, we would make a pause to pay our respects and to ask Popo to let us work on him for the day, I have done this ever since on every other active volcano I have visited
