Early morning view of the volcanic cones of Mocho (left) and Choshuenco (right) in the Chilean Lake District. View from the outskirts of the Reserva Huilo Huilo. Mocho is thought to be the source of many of the post-glacial and younger eruptions from this volcano, including the two known historical eruptions in 1864 and 1937.
