This prominent fumarole is located in the summit region of Guallatiri volcano. The vigorous fumarole lies 30 m below the summit on the western side and produces a very audible "jet-like" noise. Many solfataras are located along a 300 m section of the upper west flank of the volcano, and another five fumaroles are located on the south side of the central cone.
