The Baltic Anomaly: The Fire and Ice Theory?

The strange Baltic Anomaly has baffled the world for over a year. Recently, the Ocean X Team returned to the Anomaly in order a conduct a new investigation, spurring renewed rumors and speculations in the process. But what is it? Is it something artificial? Or is it a natural formation made from…fire and ice?

The Baltic Anomaly

On June 19, 2011, the Ocean X Team used side-scan sonar to “photograph” a massive object deep in the Baltic Sea, approximately 260 feet below surface. Peter Lindberg, co-founder of the Ocean X Team, jokingly declared “Hey guys, we have a UFO!” However, after a new expedition, the Team discovered the Anomaly primarily consisted of large rocks. The exact nature of those rocks, which we call the Circle, as well as a 985 foot runway leading up to them (the Tracks), remain mysteries.

Since that time, the Ocean X Team has gone on a second expedition, released a few photographs and some video, and provided lots of mysterious information via interviews conducted primarily with the Team’s UFO-centric Facebook community as well as websites devoted to UFOs. However, very little concrete data has emerged. Skeptics, including us, have questioned whether or not the Baltic Anomaly is a “hoax” of sorts.

The Ocean X Team has vigorously defended itself from charges of a hoax. They claim to be ordinary treasure hunters who happened to stumble upon a strange mystery. They have assured the world that they want answers just as badly as everyone else.

Outstanding Physical Mysteries?

Let’s get one thing straight…the Baltic Anomaly “evidence” available to the public is quite limited and of very poor quality. Most of the information is in the form of unsubstantiated testimony. Unfortunately, some of this testimony has changed over time (for example, the mysterious “egg shaped” hole is now referred to as a perfectly round hole). Other pieces of this testimony are highly speculative, such as reports of malfunctioning equipment and other odd phenomena. That being said, here are a few of the “physical mysteries” surrounding the Baltic Anomaly.

  • Strange Shapes: One end of the Circle has a rounded, circular shape. The top of the Circle contains numerous right angles and carved pathways which apparently resemble the shapes of “corridors,” “rooms,” and even a “staircase.
  • “The Hole: There is a hole on top of the Circle. In its initial statement, the Ocean X Team described it as “egg shaped.” More recently, Peter Lindberg, co-founder of the Ocean X Team, referred to it as “round.
  • The Fireplaces: The Team photographed several circular rock formations on top of the circle which resembled “small fireplaces.” The stones were covered with something that looked like soot. Stefan Hogeborn, one of the divers, described them as being “like four or five pearl necklaces with stones, each a few decimeters in diameter.” For reference, a decimeter is equal to roughly four inches.
  • Mysterious Stone Samples: The Team collected two stones from the area. One of the stones was apparently indigenous to the region but normally found under the Earth’s crust. The other stone was common to the mid-Atlantic.
  • Odd Materials: The Circle’s exterior was initially described as resembling sandstone. Lately, it has been described as “granite.” When divers broke off a piece, they discovered the inside was black, like volcanic rock.
  • Volcanic Activity: No known volcanoes exist in the Baltic Sea. However, the Team spotted a 50-meter tall mountain that resembles a “black smoker” several miles from the Circle. The Ocean X Team also believes magma resides underneath the Circle and in the vicinity.

Fire & Ice

There are well over a dozen theories by now which attempt to explain the Baltic Anomaly. They range from the natural (pillow lava, rock formation) to the artificial (a shipwreck, an artifact of an ancient civilization, a forgotten Nazi sub trap, and even a sunken UFO).

We’ve gone on record stating our opinion that the Circle may have been formed by several extinguished “black smokers.” We’ve also pointed out how the last Ice Age could’ve formed the “small fireplaces.” However, we haven’t really taken the time to put these pieces together into one comprehensive theory. So, here it goes…we believe the Circle was formed by “fire and ice.”

We are currently in an ice age, known as the Pliocene-Quaternary glaciation. It started 2.58 million years ago. During this period, ice sheets have advanced and retreated on a cyclical basis. To make a long story short, the area now encompassed by the Baltic Sea was heavily eroded during these cycles, eventually forming a deep basin.

While covered in ice, we believe a sort of subglacial submarine eruption took place in the area now encompassed by the Baltic Anomaly. This could’ve been accomplished via now-extinguished hydrothermal vents or via a normal submarine eruption.

Magma and/or dissolved minerals was expelled into the thick ice sheet. It was hot enough to melt out space underneath the ice. However, it wasn’t hot enough to melt a hole through it. Thus, a large subglacial mound formation known as pillow lava was created. The video below, from the movie “Pele Meets the Sea,” shows pillow lava flowing underwater off Hawaii’s coast. This particular lava erupted on land and flowed into the ocean. However, underwater pillow lava probably forms in a similar manner.

And that’s it. In other words, we think the Baltic Anomaly is most likely an ancient pillow lava formation, created by the interaction of fire and ice.

Back to the Outstanding Mysteries…

But how does the “fire and ice” theory hold up to some of the outstanding mysteries we listed above? Let’s take a look…

  • Strange Shapes: According to the Encyclopedia of Volcanoes, “the glassy surfaces of pillows are not smooth but have cracks, corrugations, and linear grooves, many of which intersect at right angles.” Also, lava pillows “are found in a wide variety of shapes including near-spherical bulbous pillows.”
  • The Hole: This could be the remains of an extinguished hydrothermal vent. Also, sometimes lava “pushes aside a portion of the outer pillow crust and drains out through the hole to form a spilled pool outside the broken pillow.”
  • The Fireplaces: The “fireplaces” might actually constitute moraines. In other words, as the ice sheets retreated from the pillow lava, small rocks slid down a cone of ice to form a circular shape on top of it.
  • Mysterious Stone Samples: The stone normally found under the Earth’s crust could’ve been driven to the surface by the submarine eruption. The other stone could’ve arrived in the area via any number of normal means.
  • Odd Materials: The chipped, granite-like surface of the Circle is consistent with what one would expect to find at a pillow lava formation. Also, the black interior could be explained by a heavy presence of sulfide. Incidentally, sulfide would also explain the substance “resembling soot” which covered the rocks dotting the exterior.
  • Volcanic Activity: The 50-meter tall mountain resembling a “black smoker” indicates the presence of volcanic activity in the region. Also, although no known volcanoes exist in the Baltic Sea, geothermal heat is actually fairly common. Regardless, if the “fire and ice” theory is correct, the volcano or black smoker would’ve existed thousands of years ago when ice lasted covered the Baltic Sea.

Guerrilla Explorer’s Take

So, there you have it. Unfortunately, the lack of concrete information makes it difficult to provide much in the way of extensive analysis. However, the “fire and ice” theory appears to explain most of the outstanding physical mysteries surrounding the Circle.

The Ocean X Team is currently on-site, investigating the Anomaly. They are expected to return in late July.

  1. Die Angabe zur Fundtiefe ist völlig falsch! Die Struktur liegt in 85 Meter Tiefe, nicht in 260 Metern.

  2. Great write up, thanks. Any idea how to explain the so called tracks in the sea floor, the existence of multiple objects seemingly originating from one point on the sea floor, and/or the lack of siltation on the object? Generally, submerged objects are encrusted with inverts, corals, etc but there doesn’t,t seem to be any.

    • There’s a couple of possible ways the ridge could’ve been formed. It could be debris scraped off the object as the ice melted. Or perhaps the melting water pushed the seabed up against the Anomaly. And if the theory is correct, multiple objects wouldn’t be that surprising. It just means magma broke through the surface in more than one place. As for the lack of silt, it could be caused by the lack of currents in that area of the Baltic Sea. Thanks for the visit!
