@bancho14344: Kerid - Iceland’s volcanic crater lake Kerid is a volcanic crater lake in southern Iceland. It formed about 3000 years ago after a magma chamber collapse. The crater spans 170 meters wide and reaches 55 meters deep. The lake is filled by rain and snowmelt, not springs. Groundwater keeps the water level steady. The crater’s reddish walls come from iron-rich volcanic rock, creating a vivid contrast. #nature #tourism #travel #voyage #Hiking #kerid #crater #lake #volcano #iceland
