Irazu gets its name from an Indian word, irstaru which appropriately means "mountain of thunder." There is a legend that an Indian chief sacrificed his daughter to the volcano gods, then later prayed to the gods for assistance in battling a neighboring tribe. The volcano gods answered his prayer by erupting, raining fire on the other tribe, and causing a mud slide to wipe out their village.
The volcano is active, although its last famous eruption occurred when U.S. President John F. Kennedy was in Costa Rica for a meeting of the Organization of American States in March 1963. I will show some closer photos of the crater during the days ahead.
