The government will continue denying it, but it's almost certain that there's a secret underground military base in the vicinity of the Colorado-New Mexico border. And it's not just owned by the government, but by extra-terrestrials, too. Paul Bennewitz, a researcher in 1980, tracked a mysterious signal from Albuquerque all the way to the site of the base, before being turned back by the real men in black.
It gets stranger from there. Aside from the frequent cattle mutilations, a US government geologist stepped forward in 1995 to tell an incredible tale. He was supervising drilling and expansion of the existing base near Dulce, when the team uncovered an underground habitation of seven-foot aliens. This led to a long and bloody battle for control of the territory, which the geologist barely survived. If they ever emerge from their hiding place, we might not be so lucky.
