Cotopaxi’s “highest” status is often debated among geographers, as it depends on how “active” is defined. However, in most competitive exams, Cotopaxi is the standard answer because of its classic volcanic shape and its very clear, documented history of frequent eruptions. Unlike other higher peaks that may be dormant or show only minor steam activity, Cotopaxi has produced devastating lahars and ash clouds in recent centuries. Its height, combined with its dangerous levels of activity, makes it one of the most monitored mountains in the South American Andes.
