Densely forested Botos cone, the southernmost of the three volcanic cones forming the summit of Poás volcano, last erupted about 7500 years ago. Following this eruption activity shifted north to the presently active crater, whose unvegetated rim is seen at the upper left. The floor of the 1-km-wide Botos maar is now covered by the waters of Laguna del Agua Fria ("Cold Water Lake").
