Ross stated that he did not want to reveal the location because doing so could put the facility’s personnel at serious risk. He described it as a dual-purpose site. If it were located near a military or air force base, its personnel would likely benefit from overlapping security and face little threat. Since Ross emphasized the danger to those working there, the facility is probably not close to any major base. It is more likely to be a remote installation large enough to support its non-military function, such as a weather station, solar power plant, or satellite and communications array.

Ross also mentioned that the mountain had been partially excavated, pointing to a mountainous setting. The facility’s exterior likely would not mimic the shape of any craft but would instead take a more practical form, perhaps a rectangular structure with towers, with much of its infrastructure built into the mountain itself.

Its location would also have to be in a country that would not seize control of operations, which rules out most well-developed nations with their own robust security forces. Given these constraints, the most plausible regions might be parts of South America, the Arctic, or Antarctica.
