Nestled in the scenic Grímsnes area in South Iceland, the Kerid Crater is a volcanic marvel that has captivated the imagination of geologists, tourists, and nature enthusiasts alike. With its strikingly vivid blue-green lake, red and black volcanic rock walls, and surrounding greenery, Kerið is a breathtaking sight that offers a unique glimpse into Iceland’s tumultuous volcanic history. This article explores the geological formation, cultural significance, and ecological environment of the Kerid Crater, providing an in-depth understanding of why this natural wonder is a must-visit destination.
Geological Formation and History
The Volcanic Origins
Kerið is part of a group of volcanic craters known as the Tjarnarhólar cluster, located in the Western Volcanic Zone of Iceland. Unlike many of Iceland’s other craters, Kerið is not the result of a volcanic explosion. Instead, it is believed to have formed when a cone volcano erupted and subsequently collapsed into its magma chamber about 3,000 years ago. This collapse left behind a caldera that later filled with groundwater, forming the lake that we see today. The relatively shallow depth of the lake, typically between 7 to 14 meters, depending on rainfall and other environmental factors, contributes to its unique color, which is a striking contrast against the red and black slopes of the crater.
Geological Features
Kerið’s geological features are a testament to the diverse and dynamic volcanic activity that has shaped Iceland’s landscape over millennia. The crater itself is approximately 55 meters deep, 170 meters wide, and 270 meters in circumference, making it one of the more accessible and easily navigable volcanic craters in Iceland. The caldera’s steep walls are made up of iron-rich volcanic rock, giving them a distinctive red hue, which is particularly vivid against the blue-green water of the crater lake. The lake’s color is influenced by the minerals in the surrounding soil, as well as the algae that thrive in the water, adding to the site’s mystique.
Age and Evolution
Kerið is relatively young in geological terms, estimated to be around 3,000 years old, which is quite recent compared to other volcanic formations in Iceland that date back tens of thousands of years. This youthfulness is reflected in the sharpness of its features and the lack of significant erosion, which has allowed the crater to maintain its dramatic appearance. Over time, the landscape around Kerið has evolved, with vegetation gradually colonizing the crater’s slopes, creating a stark contrast between the lush greenery and the barren volcanic rock.
Ecological Significance
Flora and Fauna
Despite its volcanic origins, Kerið supports a surprisingly diverse ecosystem. The crater’s slopes are home to various plant species, including mosses, lichens, and small shrubs, which have adapted to the harsh conditions of the volcanic soil. These plants play a crucial role in stabilizing the slopes and preventing erosion, while also providing a habitat for insects and other small creatures. The lake itself, though relatively small and shallow, is home to a variety of aquatic life, including algae and microorganisms that thrive in the mineral-rich water.
Environmental Impact
Kerið’s environment is delicate and vulnerable to the impacts of human activity. The increasing number of tourists visiting the site has raised concerns about the potential for environmental degradation, including soil erosion, littering, and damage to the fragile plant life that grows on the crater’s slopes. Efforts have been made to mitigate these impacts, including the installation of designated walking paths and viewing platforms, as well as educational signage to inform visitors about the importance of preserving the natural environment.
Cultural and Mythological Significance
Historical Importance
Kerið has long held cultural and mythological significance for the people of Iceland. In ancient times, volcanic craters were often viewed with a mixture of awe and fear, as they were believed to be the dwelling places of powerful spirits or gods. Kerið, with its otherworldly beauty and dramatic landscape, would have been a particularly potent symbol of the earth’s raw power. Although specific legends or myths directly associated with Kerið are scarce, the crater fits within the broader context of Icelandic folklore, where natural landmarks are often imbued with spiritual meaning.
Modern Cultural Role
In modern times, Kerið has become a popular tourist destination, attracting visitors from around the world who are drawn to its stunning beauty and unique geological features. The crater has also served as a site for artistic performances and cultural events, taking advantage of its natural acoustics and dramatic setting. In 2019, for example, a concert was held on a floating platform in the middle of the crater lake, highlighting the site’s cultural versatility and its potential as a venue for creative expression.
Visiting Kerid Crater
Accessibility and Location
Kerið is conveniently located just off the Golden Circle, one of Iceland’s most popular tourist routes, making it easily accessible for visitors exploring the country’s southern region. The Kerid Crateris approximately 15 kilometers from the town of Selfoss and about 70 kilometers from Reykjavík, Iceland’s capital. This proximity to major tourist hubs makes Kerið an ideal stop for those looking to experience Iceland’s volcanic landscapes without venturing too far off the beaten path.
What to Expect
Visitors to Kerið can expect a relatively easy and rewarding experience. The crater is accessible year-round, though conditions can vary depending on the season. In the summer months, the crater is surrounded by lush greenery, and the lake’s vibrant colors are at their most striking. In winter, the landscape is transformed into a snowy wonderland, with the crater lake often freezing over, creating a serene and ethereal atmosphere.
A well-maintained walking path circles the rim of the crater, allowing visitors to take in panoramic views of the surrounding landscape. The path is relatively flat and easy to navigate, making it suitable for visitors of all ages and fitness levels. For those who wish to explore further, a trail leads down to the edge of the lake, offering a closer look at the water and the opportunity to experience the crater from a different perspective.
Practical Information
There is a small entrance fee to visit Kerið, which goes towards the maintenance and preservation of the site. Parking is available at the entrance, and there are basic facilities such as restrooms and information boards that provide background on the crater’s geology and history. It is recommended to wear sturdy shoes, as the volcanic rock can be uneven in places, and to bring a jacket, as the weather in Iceland can change rapidly.
Kerið and the Golden Circle
The Golden Circle Route
The Golden Circle is one of Iceland’s most famous tourist routes, encompassing a range of natural and historical landmarks within a relatively short distance from Reykjavík. The route typically includes Þingvellir National Park, Geysir geothermal area, and Gullfoss waterfall, each offering a unique glimpse into Iceland’s natural beauty and cultural heritage. Kerið is often included as an additional stop on this route, providing visitors with the opportunity to explore a volcanic crater and its associated lake, which adds a different dimension to the experience.
