Alien hunter websites have been sent into overdrive after the mysterious discovery was made on Google Maps.
The claimed ‘crash site’ is around 70 miles from Roswell in New Mexico, where UFO legend has it that a flying saucer crashed in July 1947, and the US military covered it up.
The markings on the ground, seen in Google images, also include some that have been described by some conspiracy theorists as “Nazi occult symbols”.
There are several long-standing conspiracy theories about Hitler and the Nazis experimenting with the occult and making contact with aliens in secret bases, including in the Antarctic, which have fuelled speculation about the new discovery.
Pseudo-science and archaeology website Ancient Origins has picked up on the images.
Its website said: “People have claimed that the enigmatic symbol found near Roswell is the result of Nazi occultism and even alien worship, due to its proximity to Roswell, where one of the most famous UFO sightings in history occurred.”

Is this a swastika or sign of Buddha?
In 2007, the US Navy was forced into an embarrassing apology after satellite imagery exposed how the Coronado Naval Amphibious Base in San Diego had been designed in the swastika shape.
But others believe the Roswell symbols have been there much longer.
Ancient Origins added: “However, this theory isn’t widely accepted by everyone, as there are many people who believe that the enigmatic symbols spread across the land of New Mexico, date back hundreds of years.”

Some of the markings appear like ancient runes
In a blog posting he took the leap from speculation to say it was a sign pointing out a hidden underground alien base.
While others wondered why a hidden base would have such an unusual “X marks the spot” highlighting it, he said it was to warn oil drillers to steer clear and avoid the cavernous dwelling.
He blogged: “This is not a symbol of Hitler’s Nazis, but is the ancient buddha symbol that means pure goodness.
“Also in the writing in the rectangle above is alien symbols, very similar to those found at the Roswell UFO crash on small metal beams and parts.
