Iceland is renowned for its stunning natural landscapes, from glaciers and volcanoes to geysers and hot springs. Among these natural wonders is the fascinating phenomenon of Skútustaðir pseudocraters, also known as Skútustaðagígar, located in the Mývatn area in northern Iceland. These rootless craters are a testament to Iceland’s volcanic activity and unique geological formations.
What are Pseudocraters?
Pseudocraters, or rootless cones, are volcanic landforms that resemble true volcanic craters but are not directly connected to a magma conduit. They form when molten lava flows over wet ground, causing steam explosions that create crater-like depressions. This process distinguishes pseudocraters from traditional craters, which form from volcanic eruptions through direct magma explosions.
Formation and Characteristics of Skútustaðir Pseudocraters
The Skútustaðir pseudocraters were formed around 2,300 years ago during the volcanic eruption of Lúdentaborgir and Þrengslaborgir. The hot lava flowed over the wetlands near Lake Mývatn, causing steam explosions that created the craters. These craters are particularly notable because they sit on a scoria mount, adding to their unique appearance.
Visitors to Skútustaðir can observe various types of pseudocraters, from grassy hills to more distinct crater bowls. Some pseudocraters have grassy volcanic bowls, while others display lava spatter and scoria from explosive activity. This variety provides a captivating landscape for geologists and tourists alike.
Visiting Skútustaðir
Skútustaðir is easily accessible, located right by the road with paths leading through the area, offering an engaging walk among the craters with views of Lake Mývatn, Iceland’s fourth-largest lake. The area around Lake Mývatn is rich with natural beauty and geological interest, making it a popular destination for travelers exploring the northern regions of Iceland.
The Skútustaðagígar pseudocraters were designated a natural monument in 1973, covering an area of approximately 70 hectares. This protection ensures the preservation of these unique geological features for future generations to study and enjoy.
Other Notable Pseudocraters in Iceland
While Skútustaðir hosts some of the most impressive pseudocraters, Iceland is home to several other notable clusters of these formations:
Rauðhólar Pseudocraters: Located in the Heiðmörk Nature Reserve near Reykjavik, these 5,000-year-old craters are distinguished by their dark maroon color. They were preserved as a natural monument in 1974 after part of the area was used for landfill materials.
Landbrotshólar Pseudocraters: Found in the Katla UNESCO Global Geopark in South Iceland, this extensive area covers around 50 square kilometers and likely formed during the Eldgjá eruption (934-938 AD). These pseudocraters vary in shape, from cones and pyramids to round bosom-like formations.
Álftaversgígar Pseudocraters: Situated near Mýrdalssandur in South Iceland, these craters formed during the Eldgjá eruption. They act as natural barriers against glacial floods from the Katla volcano and were protected as a natural monument in 1975.
Frequently Asked Questions About Skútustaðir
What is a pseudocrater?
A pseudocrater is a volcanic landform that resembles a crater but forms from steam explosions when lava flows over wet ground. Unlike true craters, pseudocraters are not connected to a magma conduit.
What are the false craters in Iceland?
The false craters in Iceland, or pseudocraters, include notable formations like the Skútustaðir pseudocraters in the Mývatn area, Rauðhólar pseudocraters near Reykjavik, and Landbrotshólar pseudocraters in the Katla UNESCO Global Geopark.
