It appears to be at the top of a mound and definitely looks more impressive from a distance. Some scientists have described this as a natural
formation created by the harsh geological effects that occur near the poles. As the ground freezes and unfreezes, it is subjected to the same law that
causes your water to spin after flushing the toilet.
The freeze-thaw cycle of permafrost can cause sediment to churn and separate by grain size that can cause boulders or large rocks to produce stone
circles or polygons on low slopes.
The same effect has been viewed from space on the surface of Lake Baikal in Siberia. It was taken from the ISS in 2009. The Coriolis force has an
effect both underneath and above ground.
Methane emissions can create a rising mass of warm water that begins swirling in a circular pattern because of the Coriolis force, or the
phenomenon caused by the Earth's rotation that also helps create cyclones.
"Once the water mass reaches the underside of the ice on the surface of the lake, the warm water melts the ice in a ring shape," said Marianne
Moore, a marine ecologist at Wellesley College in Massachusetts who has spent much time studying Lake Baikal with Russian researchers. The lake is the
largest (by volume) and deepest fresh water lake on Earth.
A similar ring structure was observed and photographed in the south pole region of Mars. The picture of the ice ring was first taken by the Mariner
and Viking probes.
High resolution images were taken later by the MRO. The ring is 4 kilometers across and the hill (not pyramid), like structure in the middle is called
Both formations were likely created by the same process and may have helped formed the mysterious "Marshenge" being discussed. I would look at the
evidence presented before jumping to conclusions, but would love to hear what other member think. Another natural formation or a remnant of history
from past civilizations?
