All it takes is one drive through Arizona to realize that very little of the land can be owned or developed. A certain amount are tribal lands, National Parks, and BLM secured areas. You can drive for hours without a sign of life.
Because we have unlimited 160-degree sky to view UFOs and because we have lands where we aren't supposed to be poking around, there is some natural curiosity if we have secret underground bases hidden from view.
Roosevelt Lake Area - Tonto National Forest
LINK: An email was sent by the department to all rangers on December 30 2013, detailing the extraordinary encounter.
The email said: "David received a call this morning at the front desk from a male caller reporting the construction of a secret government installation upstream from the Salt River Canyon past Pinal Creek (Upstream from Roosevelt Lake).
BRADSHAW RANCH, SEDONA
The Bradshaw Ranch has been associated with Bigfoot, UFOs, a potential portal, strange lights, a possible hidden base. When a lot of people witness a lot of weirdness, it's going to make us compare stories.
LINK: Located at the junction of Hartwell Canyon and Loy Canyon, 12 miles outside Sedona in the Verde Valley, the famous Bradshaw Ranch is padlocked now. The rumor is that it was confiscated by the U.S. Government in May of 2003 for $3.5 million dollars because it housed one of the most powerful inter-dimensional portals on the planet.

Tucson - Bicyclists in a race were going through the desert and took a break when a most unusual being, some would refer to as a reptilian, was witnessed.
LINK: ...all of a sudden we see this long figure walking across the trail. He is maybe about 6-foot tall, very very skinny, and it had an awkward gait, like a monkey…or a man with a disease, almost robotic, kind of...He stopped and it made eye contact with me and I could see him clearly. The eyes were kind of like a snake’s, but black and with a yellow stripe in the middle of the eye. It had green and red scales on the face and head. The red color was kind of like the same as the desert sand there, and it looked like it had a sandy texture too. It didn’t have a nose, only two holes on it. I couldn’t see any ears or hair. A red mouth that looked like it had blood around it, but it didn’t look like it was bleeding, it looked like a pattern. It reminded me of a chameleon, but it looked like a person too...the creature raised its “long arms with strange looking claws that looked like a branch full of thorns” and waved at them, emitting a loud chattering sound with its teeth. Then it rapidly ran away, in a fashion that reminded the witness of “a lizard trying to hide.”
There is a fantastic site that covers Arizona Underground called Arizona's Underground. You can find other potential sites like Fort Huachuca, the Grand Canyon, and more!
