This aerial photo from the north overlooks the Rincón de la Vieja summit cone complex in NW Costa Rica. A gas plume rises from the acidic Cráter Activo lake, and erosional gullies have formed across the flanks. The darker Laguna Fria beyond the Cráter Activo is a non-volcanic lake formed between the vegetated Rincón de la Vieja crater (far-left) and the ridge extending to Santa María to the upper left of the photo.
