Klausturhólar - Kerið, Iceland

Iceland, Klausturhólar- Kerið, a volcanic crater lake in the southwestern part of Iceland, “is approximately 55 m (180 ft) deep, 170 m (560 ft) wide, and 270m (890 ft) across. Kerið’s caldera is one of the three most recognizable volcanic craters because at approximately 3,000 years old, it is only half the age of most of the surrounding volcanic features. While most of the crater is steep-walled with little vegetation, one wall is sloped more gently and blanketed with a deep moss, and can be descended fairly easily. The lake itself is fairly shallow (7–14 metres, depending on rainfall and other factors), but due to minerals from the soil, is an opaque and strikingly vivid aquamarine.”
