The twin volcanoes of Arjuno (right-center) and Welirang (left), seen here rising NE of cultivated land at their feet, anchor the SE and NW ends, respectively, of a 6-km-long line of volcanic cones and craters across a broad valley across from Tengger caldera. A line of pyroclastic cones cuts across the southern flank of Gunung Arjuno and extends to its eastern flank. Fumarolic areas with sulfur deposition occur at several locations on Gunung Welirang.
