The Dulce papers were documents which were leaked by former facility workers. The papers details the following about the base.

Description
The multi-level facility at Dulce goes down for at least seven known levels, and is reported to have a central HUB which is controlled by base security. The level of security required to access different sections rises as one goes further down the facility. There are over 3000 real-time video cameras throughout the complex at high-security locations (entrances and exits). There are over 100 secret exits near and around Dulce. Many around Archuleta Mesa, others to the south around Dulce Lake and even as far east as Lindrith. Deep sections of the complex connect into natural cavern systems.

Levels
Some of the following information can also be found in some of the other sections and categories on the page.

Level 1
Level 1 is a parking garage and street maintenance level. All vehicles in the Dulce facility are stored here. No one drives in or out without seeing security and giving both their card and access number. It has been said that on the roads leading in to the garage there are magnetic sensors like those located around Area 51.

Level 2
Contains the garage for trains, shuttles, tunnel-boring machines and disc maintenance. This is where most of the shuttles are located as well. Most of the tunnel systems lead to more underground alien bases. Area 19, Area 51, Plant 42, Green river, Dugway, Edwards AFB, Page, an Arizona facility, to facilities below Taos, N.M.; Datil, N.M.; Colorado Springs, Colorado; Creed, Colorado; Sandia' then on to Carlsbad, New Mexico, the Denver International Airport, and some to Los Alamos in an underground base, which holds an Aurora spy plane.

Level 3
Has housing and complexes for workers and test subjects. This area is also a major control area, where most of the computers are centered and the whole base is controlled.

Level 4
Level 4 includes human-aura research, as well as all aspects of telepathy, hypnosis, and dreams. Some say they know how to separate the bioplasmic body from the physical body to place an ''alien entity'' life-force-matrix within a human body after removing the ''soul'' lifeforce-matrix of the human. Here, they have reportedly been able to unlock Telepathy and Psychicism, allowing humans and animals to use force without using muscles in the body.

Level 5
Holds alien housing for the ''Grey'' species and the ''Reptoid'' species. These two species live in the base, over five thousand to be exact. All of them are used for research, both their own and human.

Level 6
Level 6 is privately called Nightmare Hall. It holds the genetic labs, where experiments are done on fish, seals, birds, and mice that are vastly altered from their original form. There are multi-armed and multi-legged humans and several cages (and vats) of humanoid bat-like creatures as tall as 7-feet. The aliens have taught the humans a lot about genetics; things both useful and dangerous. This level also is for cloning of the Greys, who can not reproduce through usual methods and must clone to keep a steady population.

Level 7
Within Level 7 you may encounter humans in cages. Row after row of thousands of humans, human-mixture remains, and embryos of humanoids were kept in cold storage. A worker says,

I frequently encountered humans in cages, usually dazed or drugged, but sometimes they cried and begged for help. We were told they were hopelessly insane, and involved in high-risk drug tests to cure insanity. We were told to never speak to them at all. At the beginning we believed that story. Finally in 1978 a small group of workers discovered the truth. That began the Dulce Wars.
