The Irazú summit crater is about 700 m wide and nearly 200 m deep and has been the source of most of Irazú's historical eruptions. Geothermal activity is frequently observed around of the lake, and the water color varies with changing atmospheric conditions. Photo by Lee Siebert, 1998 (Smithsonian Institution).
