The flat area to the left is Alun-Alun, the uppermost of four large craters on Papandayan volcano. The v-shaped valley in the center of the photo extending to the NE is the breach left by collapse of Papandayan volcano in 1772. The volcano in the distance on the left horizon is Gunung Guntur, another historically active volcano bordering the Garut Plain.
