An island off the coast of Antarctica. A frozen landscape. A mysterious trail starting from a mountain. A strange rock-like object at the end of it. You might think avalanche, but some people on the Internet think differently. For them, an alien spaceship has crashed there (cue The X-files theme music).

This elaborate “theory” was posted in a video by UFO-truther YouTube channel SecureTeam10 and is based on satellite images from Google Earth. They manage to pull a 13-minute discussion on how this cigar-shaped object not only crash-landed there but also damaged the nearby peak from which the trail originates.

“What appears to me at least to be some sort of massive elongated or cigar-shaped object that at some point – and we don't know when – came to a screeching halt in the snow leaving behind it an almost 1,000-meter-long [3,280-foot-long] trail,” said the author in the video.

“We can see this massive object is directly next to this huge mountain peak here and you'll notice that leading back from the trail that this object created, moving across the snow and ice, it appears as if there's some damage that has been done to the side of this mountain where we can see this wave of debris extending outwards from the mountain itself.”

I have many questions. How did the spaceship hit the mountain to create a limited-debris area but manage to move hundreds of meters more? Why is the spaceship already covered in snow and ice when the trail is still perfectly visible? How can anyone think that this is anything other than an avalanche?

The location of the “crash” is on South Georgia Island, part of a British Overseas Territory in the South Atlantic Ocean that also includes the South Sandwich Islands. The territory is inhabited by just a couple of dozen people, including government officials and scientists and support staff from the British Antarctic Survey.

“[South Georgia] is the exact same surface structure as Antarctica, mountainous, covered in ice and snow. Nothing there. Completely barren,” explains the video. The island has 26 native species of vascular plants and is home to many bird species including king penguins, albatrosses, and more. Seals and whales are often seen in the waters surrounding the island too. It is often visited by cruise ships and is the resting place of Anglo-Irish polar explorer Ernest Shackleton.
