There are 3 barrel like conduits that are approximately 4.5-5.5 meters (15-18ft) high and 5.5-6.0 meters (18-20ft) wide. During normal flow periods, the river flows freely into the far right conduit (west tunnel). The other 2 tunnels are used for periods of swelling and overflow. If research is correct, this is a section built after the original sections, proposed and recommended by Calvin Hendricks himself.
Once you take the decision to enter into the Mouth of Jonesy, your senses will quickly be inundated by unworldly external stimuli. The world around you will quickly transform its self into a foreign unforgiving environment. The explorer will quickly realize, “Humans do not belong in here, this is a no mans land”. Your instincts are not far off as this is an area on earth that was not designed for human life. If you scream, no one will hear you. Jonesy will swallow your reverbs. The explorer may notice the most significant and immediate environmental change is the overwhelming acoustics that this part of earth produces. At this point, you are positioned directly underneath of an Interstate. Shortly thereafter that the roar of diesel locomotives passing over the earth, 20 meters above your skull, penetrates your chest.
Looking back up North into Jonesy’s Nares. AVOID on the left.
A strong steady wind sweeps the face of the explorer. The breath of Jonesy himself. The natural barometrically-driven breathing of the tunnel. As air quality was one of the chief safety concerns of the explorer, this cool, dry & non-malodorous wind would provide a short lived psychological comfort of what lies down below.
As the explorer continues to push forward, the tunnel takes a gradual, slight bend to the east (bending left). The acoustics begin to change significantly. Which in turn just intensifies everything. The explorer would start hearing a dull yet overwhelming, roar that only increases in decibels as they get nearer to the source. Adrenaline glands running on full blast, the tunnel starts to straighten met with a swift downgrade. At this point, it is evident that the source of this noise is water that lies down at the bottom of this concrete downgrade. Depending on what lighting gear you have, you will notice there is an straight, divider at the bottom. The ceiling height begins to increase as the explorer travels down this decline, onward to the next section.
At the bottom of this decline brings the explorer to Junction Chamber 1 of this massive storm sewer. Its called Tripple Barrel Hall. Its where the 3 barrel conduits/tunnels turn into 2 massive ones known as Penn Stations’s Chasm Halls. It is estimated to be about 150-200meters deep inside or approximately a 2 minute walk.
Do not try to access these Conduits / tunnels / storm sewers! It’s dangerous. Getting caught within, or even trying to get in, probably could be considered a serious offense. Especially after the events of 9/11. These pages provides a complete virtual tour of the system that you can enjoy without risking your life or a criminal record. We’ve already risked our life, so that you can explore virtually from home… so stay safe, and stay away!
