1.2.1 Rabbit holes: The covert underground infrastructure serves many functions. Among these are strategic storage of materials and weapons, clandestine research and production facilities, alternant basing for military personnel and equipment, surface environment control systems (atmospheric lensing, synthetic earthquakes, weather modification, civilian population control, etc.), and of course sheltering essential government personnel during time of national crisis or war. This list is not complete, it is only indicative of the diverse ways in which the underground infrastructure is utilized. It should be obvious that many of the uses listed above require both support from, and easy access to, the surrounding surface communities. I call these underground access points "rabbit holes", and they represent a key detectable feature of the underground infrastructure. It should also be obvious that many of these uses require the facilities to be interconnected by a network of tunnels. The construction of these tunnels creates surface evidence of their existence, albeit transitory. From the perspective of detection, the transitory nature of the evidence makes tunnel construction less useful than covert underground access points, however as we shall see, the evidence itself is far more compelling.

The following is a list of rural underground access point indicators. 1. A well maintained branch road leading to a little used park or recreational facility. 2. Electrical power lines that are routed near facility, when such routing results in longer line length and/or routing over a natural obstacle (mountain, river, etc.). 3. Electrical power lines or substations much larger than visible local load requirements. 4. Large reservoirs that serve no apparent useful function. Example: not needed for flood control or civilian water supply, or that have larger capacity than is required for presumed function. 5. The presence of truck traffic on rural roads with no known destination, or inappropriate truck types for apparent destination. 6. A public park or recreational facility that is maintained at a level well in excess of other nearby facilities, especially if facility less well known or used than other nearby facilities. 7. Public facility personnel (park rangers, etc.) that are overly nosey and/or suspicious of your activities, especially if personnel occupy the site on a 24/7 basis. 8. Public park or recreational facility where part of facility is fenced off, or accessed by a gated road, or otherwise made inaccessible to the general public. 9. The presence of inappropriate or unusual structures and/or construction methods. Examples: small cinder block building with an electrical power feed normally used on major office buildings. An unmarked, but well maintained trail in public park. An old building (possibly abandoned) with a new door, and expensive lock. 10. People at camp grounds that seem out of place. Example: improperly dressed, or using inappropriate equipment, or having unusual accents (these are people taking a recreational break from underground facilities). 11. Well maintained roads that are not shown on maps, or follow a different route than shown on maps. 12. A noticeable lack of wildlife (birds, small animals, insects, etc.) in a location that would normally support a large wildlife population (see 1.2.4 preface). 13. Any of the applicable indicators listed under urban rabbit hole detection. Example: unbalanced traffic flows, etc.
