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.

The linear grayish lava flow extending into two lakes at the center originated from the Achín-Niellu cinder cone in the snow-covered area at the bottom-center of this NASA Space Station image with north to the upper left. The distal end of 7.5-km-long flow forms a large delta into Lago Epulafquen. A cinder cone separates this lake (known in the Machupe language as "Two Lakes") from the large lake at the upper right, Lago Huechulafquen. The lake at the right-center is Lago Curruhué.

The blocky, partially forested Escorial lava flow in the foreground is seen from the north on a boat on Lago Epulafguen. The flow originated from the Achín-Niellu pyroclastic cone (center), which is part of the Huanquihué group of young basaltic volcanoes in Argentina near the Chilean border south of Lanín volcano. The Escorial lava flow was erupted about 200 years ago, and local residents recount oral histories of the eruption, which was observed by their grandparents.
