The blocky, partially forested Escorial lava flow in the foreground originated from Achín-Niellu (also known as Achen Niyeu or Cerro Escorial) pyroclastic cone (center). The Escorial lava flow traveled north into glacial Lago Epulafquen, forming a prominent lava delta. Oral accounts of local residents stated that the flow was witnessed by their grandparents, who described the eruption of smoke, ash, and lava that changed the shoreline of the lake.
