Densely forested Botos cone, the southernmost of the three volcanic cones forming the summit of Poás volcano, last erupted about 7500 years ago.  Following cessation of eruptions at Botos volcano, the magmatic focus shifted to the presently active summit crater.  The floor of the 1-km-wide Botos maar is now covered by the waters of Laguna del Agua Fría ("Cold Water Lake"), also referred to as Laguna del Poás. Photo by Ichio Moriya (Kanazawa University).
