This aerial photo from the north overlooks the summit cone complex of the Rincón de la Vieja volcanic massif, the largest volcano in NW Costa Rica. A steam plume rises from the acidic turquoise-colored lake of the Active Crater, and erosional gullies cut its tephra-mantled slopes. Dark-colored Laguna Fria beyond the Active Crater is a non-volcanic lake formed between the forested Rincón de la Vieja crater (middle left margin) and the ridge extending to Santa María cone at the upper left margin of the photo.
