Thousands of people, one after the other, climbed to the top of a dormant volcano in Guatemala over the weekend, ascending the 12,352-foot slope of the Volcan de Agua (Volcano of Water).

They weren’t on an adventure excursion though. It was a mega protest against domestic violence, which included 12,000 women, children, and men (including Guatemala’s new president Otto Perez Molina).
