This 20-m-high conical hill is a hummock that is part of a massive debris avalanche deposit produced by the collapse of Gunung Gadung, a stratovolcano on the west side of Raung volcano. The hummocky topography produced by the massive landslide extends many tens of km from the volcano. Photo by Lee Siebert, 1995 (Smithsonian Institution).
