From the London Daily Mail [caution, tabloid]:
Our world is full of many confusing oddities, from a ‘UFO-like disc’ in New Mexico to a secret ‘doorway’ in Antarctica. Now, people are being left concerned by a mysterious triangular tower stationed at Area 51 in the Nevada desert. The imposing sci-fi worthy structure, about 80 miles northwest of Las Vegas, is circulating online after being spotted on Google Maps.
