Kerið is a volcanic crater lake located in the Grimsnes area, along the Golden Circle. It is one of several crater lakes in the area, known as Iceland’s Western Volcanic Zone. The caldera, like the other volcanic rock in the area, is composed of a red (rather than black) volcanic rock. The caldera itself is approximately 55 m deep, 170 m wide and 270 m. 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, but due to minerals from the soil, is an opaque and strikingly vivid aquamarine.
Yesterday, when I’ve been at the crater it has been very windy and rainy, so my pictures have been a bit off -I tried to pick the 2 best ones.
