Strange hollow holes in the ancient lake of Iceland

The current scene is the result of intense volcanic eruptions that took place thousands of years ago. In the lake, there are more than 50 small islands called Pseudocraters, looking like hollow pits.

Pseudocrater looks like a real crater, but in reality it is not.This special terrain is created when molten lava spreads on a wet surface.For example, lava flows through a swamp, lake, or pond causing a steam explosion through the lava.

Explosive gases break the lava surface in a way similar to a groundwater eruption and flying debris accumulate in the crater as a special feature that may appear very similar to the actual crater.

Pseudocraters are also known as non-rooted cones because they characterize the absence of lava ducts that connect beneath the surface of the earth.

The ancient site for the formation of Pseudocraters is the area of ​​Myvatn lake located in northern Iceland, formed 2,300 years ago due to the eruption of basalt lava.

Lava has flowed into the valley of Laxárdalur to the lowland area of ​​Ahaldalur, where they are pushed into the Arctic Ocean, about 50km from Myvatn Lake.

There was a large lake in this area at the time, the predecessor of Lake Myvatn today.When glowing lava encounters some flooded lakes, it becomes cold and settles to the bottom of the lake.The next steam explosions tore the lava into small pieces thrown into the air, along with some lakes.

Due to repeated explosions in several locations, the crater group was formed and now dominates the landscape on the shores of Myvatn Lake, as well as forming several islands in the lake.

Pseudocraters Myvatn appears in some groups around the lake and as an island in the lake.

A group of such craters in the Skútustaðir area on the southern coast of the lake is protected as a natural monument and a favorite tourist destination and frequently visited.

Another group of Pseudocrater in this lava field is currently located in the valley of Laxárdalur and Alftaver district.

Pseudocraters were also discovered in Mars's Athabasca Valles area, where lava flows into the boiled groundwater in the rocks below.
