Sub-Global System. Deep Underground Military Bases. Dulce Base. Mariana Station. Drop any info, theories, rumors about underground tunnels/cave systems and subterranean transit. There are over one hundred inner-earth cities and city-sized government/military bases. The easiest and most common method of travelling between underground cities or bases, is the Sub-Global System, made up of the Subterranean Highway and the Trans-Planetary Subway, a series of underground trains and roads in tunnels that run underneath all the oceans and all the continents and connect all the cities and several of the bases. The trains, which look very much like a subway train, are run on an electromagnetic cushion of air so they never actually touch the sides of the tunnel. This cushion creates a force field without friction and therefore they can achieve very high speeds, the highest of which ever recorded was mach 200.

The Subterranean Highway in America is like a network of interconnected underground freeways.
These highways depend mostly on electric motors and have paved roads similar to surface-level highways.
Beneath the Subterranean Highway on a much deeper level is the VHST Trans-Panetary Subway, mostly for freight and high-clearance passengers. The Trans-Planetary Subway has checkpoints at each country entry. There are shuttle tubes that shoot the trains at incredible speeds using a mag-lev and vacuum method. Trains or smaller “Pods” travel at speeds that exceed the speed of sound.
The Trans-Planetary Subway is used by shadow-governments, their black ops forces, and favored corporate entities. Together the Subterranean Highway and Trans-Planetary Subway makeup the “Sub-Global System” of underground transit. Every state in the U.S.A. has entrances to the Subterranean Highway and Trans-Planetary Subway. Frequently, the entrances are camouflaged as sand quarries, or mining operations. Other complex access-points are found under military bases. New Mexico and Arizona have the largest amounts of entrances followed by California, Montana, Idaho, Colorado, Pennsylvania, Kansas, Arkansas and Missouri. Of all the states Florida and North Dakota have the least amount of entrances. Wyoming has a road that opens directly into the subterranean freeway. That road is no longer in use, but could be reactivated if they decide to do so, with minimal cost. It's located near Brooks Lake.

Construction & Geology

Excavation: Large-diameter TBMs (tunnel boring machines) with integrated shielding and spoil conveyor systems were adapted from post-war military mining projects. Early tunnels were cut in multiple stages: pilot bores, enlargement passes, then full lining.
Lining & Support: SH tunnels use fiber-reinforced concrete with polymer waterproofing membranes; TPS tubes use multilayer composite shells (steel-carbon-ceramic) to handle internal vacuum and external lithostatic pressures at depth.
Geological Stability: The SH level is routed through softer strata and sedimentary layers where possible to reduce excavation cost. TPS routes prioritize the most stable continental plates to avoid high seismic zones, with deep-ocean segments anchored in basaltic crust.

Pod speeds in operational corridors are comparable to airliner cruise speeds (~900–1,200 km/h); higher speeds are technically possible but limited by thermal expansion and braking energy requirements.
SHW roadways are paved with steel fiber-reinforced concrete, which resists rutting from constant heavy axle loads and has reduced curing shrinkage.
Ventilation systems in SHW follow longitudinal airflow design, with jet fans mounted in the crown of the tunnel every 200–500 m. Flow is reversible to handle vehicle fires or chemical spills.
Electrical power is supplied via high-voltage DC trunk lines embedded in the tunnel lining, converted to AC locally at service caverns. This is standard for minimizing resistive losses over long distances.
Entrances are often disguised as aggregate quarries, industrial yards, or military motor pools, with angled access ramps leading to pressure-rated portals.
Florida and coastal deltas have fewer SHW portals due to high groundwater tables; deep access shafts in these regions require ground freezing or slurry walls during construction.
Every 10–15 km, SHW includes cross passages between parallel tubes for evacuation — a legal requirement in modern tunneling.
VHST tubes are lined with steel-reinforced precast concrete segments with an internal diameter of 8–10 m, fitted with expansion joints to absorb rock creep.
Maglev levitation uses superconducting magnets cooled by closed-loop cryocoolers; the track system is a linear synchronous motor embedded in the tunnel wall.
Pressure locks in VHST stations are multi-chamber systems to equalize between vacuum and station pressure without stressing seals.
Oceanic segments are anchored into bedrock using post-tensioned anchors drilled into stable basalt or granitic shelves, with grout injection to prevent corrosion.
Geotechnical monitoring includes fiber optic strain sensors, microseismic arrays, and ground-penetrating radar for void detection ahead of tunnel boring machines (TBMs).

Flood prevention is handled by sump pumps discharging to deep saline aquifers via cased boreholes; this avoids regulatory issues with surface water contamination.
Vibration from VHST is minimal because maglev guideways produce no wheel-rail contact; most noise is aerodynamic and contained within the tube.
Thermal expansion of long tunnel segments is managed with sliding segment joints and steel liners that allow up to 10 cm of movement per 1 km section.
LAMIS (Layered Autonomous Mobility Integration System) is a real-world style traffic control network that optimizes speed and separation between pods or convoys, similar to Positive Train Control systems in high-speed rail.
In seismic areas, flexible coupling sections in VHST tubes allow for up to 1.5 m of lateral displacement without rupture.
Maglev braking uses eddy current brakes and regenerative capture, with energy stored in large underground flywheels or supercapacitor banks.
Under major cities, tunnels follow deep alignment under existing transit corridors to simplify right-of-way acquisition and minimize disturbance.
Construction materials are brought underground via vertical supply shafts spaced every 5–10 km; once complete, these shafts are sealed or repurposed as ventilation stacks.
Maintenance crews use battery-electric service vehicles in SHW to avoid diesel exhaust buildup.
VHST tube interiors are kept at low humidity to prevent frost formation on cryogenic equipment.
The deepest known SGS segment in North America runs under the Rocky Mountains at ~3.8 km depth to avoid high-relief surface tunneling.
Long-distance SHW convoys are scheduled in platoons, allowing maintenance crews to close segments between traffic waves without disrupting flow.

Real-time tunnel health is monitored by distributed acoustic sensing using telecom-grade fiber in the tunnel wall, detecting anomalies like joint cracking or water ingress.
Large military bases have direct SHW/VHST interchange caverns allowing for containerized cargo transfers without surface exposure.
Camouflage infrastructure often uses fake company registrations and short-term land leases to mask portal ownership.
The longest continuous SHW segment without a surface access point in the U.S. runs over 400 km between Arizona and northern California.
VHST travel times between U.S. west coast and northern Europe are estimated at under two hours, assuming direct high-speed corridor use.

Obviously a way for the elite to escape a cataclysm they know about but are keeping to themselves. I believe it happens cyclically.
My current understanding is what I would refer to as "the harvest". The elite humans work with extradimensional entities and this planet is a farm. Life, particularly our species, is the produce. More sinister, our "loosh", or whatever satisfaction these beings get out of their sadism, is the produce.
The most powerful and highest ranking of humanity is spared come harvest time, and from them the seed for the next batch is derived. Think the symbolism of the phoenix. They are also given special privilege and power, or access to power such as advanced technology, by these beings in exchange for their part in the intentional guiding of humanity in each interim as well. They also occasionally visit for a sampling or small indulgence in the way of animal, human, or child sacrifice. If you are of the variety of man who offers these things to them, they empower you to do it more and to return the favor. The beings may also walk among the elite, disguised as humans, I am not sure. But what is clear is their sadism. They love blood, they love agony, they bathe in the most twisted physical and psychological torture of lesser beings in what way we can probably only equate is something like orgasmic sexual pleasure to them.
When the planet is deemed ripe for their purposes, the beings descend, and harvest our suffering in the most horrific of ways. The time is coming soon, I fear. Do whatever you can not to be taken away by them, as they will likely keep you as an eternal subject. Flee or hide, and die someplace well-hidden.

>>40872293
What signs/patterns do you think indicate the next harvest is approaching?

>>40872329
Historically speaking, we are already way past due. This will be the longest-coming and biggest harvest on this planet so far. In all likelihood it has been postponed in part through negotiations by some unexpected agents in the US government, otherwise not in the know, who managed to make contact with the entities; who were likely surprised and also amused enough to humor them. It's nothing more than edging to them. That agreement has an expiration date though, and certain conditions, such as that the entities will not risk allowing the crop to be wiped out or tainted by nuclear war, so risk of nuclear war is a big one.
My phone is dying and I'm at work but I can explain more later.

>>40872329
So any considerable nuclear exchange will likely trigger the harvest, that is if we manage to actually pull one off. Chances are just as good they'll intercept or disable any nuclear weapons we attempt to use.
Aside from that not much else I can think of frankly. The elite will be going into their dumbs and shelters, but to know who is an insider and where they'd be going is impossible, not to mention that they'd intentionally be slipping away unnoticed.
They can decide to reap whenever. You imagine there would be some highly specific plan, but I this world is just one of many. We are like one apple in a whole orchard. While they surely visit and watch, or get alerted by the elite when something is threatening the crop, we are rather quite insignificant. Like one meal is for you.
The last thing I can think of is the freemasons. The masons are the lowest in the hierarchy of those in the know, if they are at all, the majority certainly are not in the know. I don't think they even get spared, they are just the peons who build the safehouses and bunkers for the elite. But maybe if you can befriend any, you may be able to get an early sign from their activities.
Also, the structures they build have certain qualities with extradimensional significance. I am not saying that they "keep out" the entities, but the entitites see and understand masonic workmanship and MIGHT leave it alone. So theoretically, if you were to inhabit such a structure, or incorporate masonic symbolism into your home, etc, you MAY be spared. Probably notnthough, just a hail mary. Pretty much everything on the surface is fair game, the masonic structures are really more like signal markers for the elite, often to show the entities a place to come for sacrifice or shenanigans during interims, but so too are safehouses for the elite often within or underneath such places. Masonic symbolism is likely the only positive association you can hope could possibly get you spared.

And from where does this information originate?

>>40874062
For me, the anon talking about the sadistic extradimensional harvest. It is what I have been able to piece together centered around deathbed confessions of a glowie freemason family friend a couple years back. CIA, but that's about as much as he ever said about his career except a few approved stories that had nothing to do with anything. Straight up refused to talk about anything no matter how much we asked, he was not pernitted and I think living with himself and his family under threat. I thought he must've been part of some shit like political assassinations or something. He was not allowed to retire, and had to report for regular interrogation+polygraph until he was bedridden and dying. I think his death was even hastened to avoid potential confused, drugged, or demented spilling of secrets. He wasn't like that when he told me, he was coherent and very intentional.
A lot what I say I base on what I've pieced together around the core of his claims as well, but I believe it. You don't have to.
I think he told me because we were very close, and I might be the only person to recognize that he was not full of shit or losing it. Also because I am young, and he believed the shit would go down while I was still alive.
The nost haunting thing he told me to burn the bodies of loved ones and to try to die myself somewhere I wouldn't be found, because they have been observed as being able to either reanimate or possess corpses, or perhaps both.

Ley lines are hypothetical, straight alignments of ancient structures and landmarks, proposed to be connected by invisible energy pathways according to Britannica. The concept originated in the early 20th century with Alfred Watkins, who believed these lines represented ancient trackways or navigational routes. While not accepted by mainstream science, ley lines have become a popular concept in New Age and spiritual circles, often associated with earth energies and sacred sites.

That one at the top of Minnesota, I know where that is geographically. Ive been to the nearby town (Baudette), and I didn't even think to look for it until I returned home. Next time I'm there, should I try and find it, bros? And if so, what should I look out for, any way to identify the entrance at all?

Very intriguing and I do believe you. I took care of a man who was also a 33 degree Mason until he died at 97. He seemed ashamed of his affiliation. Also, would this indicate that these so called “aliens” are in fact extradimensional demonic entities? If so I assume they’ve been among us a long time
