This landslide has been subdivided into four facies and features landforms like levees up to high, longitudinal ridges and a run-up mark on Cerro Rosado. Such ridges may be associated with uneven underlying terrain. The surface of the slide is covered by lava bombs less than long, blocks exceeding width, cobbles, and gravel-like rocks. Close to the collapse scarp on Llullaillaco the largest blocks with sizes of up to are found. Overall, the margins of the landslide are very crisp and the surface covered by hummocks.
