THE NORTH PACIFIC “DOME”
A circular feature in the North Pacific, described in online reports as roughly two miles wide, is drawing attention again after its Google Earth image resurfaced on Reddit. The formation appears at 49°50′43″N, 140°13′21″W, alongside what looks like a winding trail across the ocean floor.
Look closely at the area extending to the left of the rounded feature. A broad curve runs through the surrounding terrain, with a dark edge that makes its shape particularly noticeable. The formation’s position near one end gives the impression of something that has travelled along that route, an interpretation that has prompted speculation about an enormous object moving across the seabed.
The story has been circulating for years. Mysterious Universe covered it in March 2017 under the headline “Massive Circular Object Appears to Move on Pacific Floor,” and SURFER returned to the same location in June 2025. Now another audience is encountering the image and asking what might account for its unusual appearance.
THE 4CHAN UNDERWATER FACILITY ACCOUNT
The image also brings to mind the anonymous 4chan poster who, in April 2023, claimed involvement in UFO recovery and analysis. Their account described a “mobile construction facility that hides in the ocean,” manufacturing smaller craft for specific assignments.
According to the poster, this facility operated primarily around the Bermuda Triangle in the Atlantic. It allegedly produced craft with different shapes and onboard equipment depending on their intended purpose, functioning as a carrier with manufacturing capabilities. The facility itself could relocate underwater, and the poster said their team suspected it was controlled by artificial intelligence.
One exchange in the thread is worth revisiting here. Asked whether additional facilities might account for UFO activity off the Americas’ west coast, the poster said they suspected others could exist, while explaining that their own work had focused on the Atlantic.
For readers familiar with that account, the North Pacific image offers an intriguing visual companion to the speculation: an enormous underwater installation capable of moving through the ocean while manufacturing and deploying its own vehicles.
I’d like to see this particular stretch of seabed in much greater detail, especially where the apparent trail approaches the circular feature. Anyone with older captures of these coordinates, original survey imagery, or earlier investigations of the site, please share them.
