Elbs Aperture

Early June, 2016
This find is truly an example of spontaneous Underground Urban Exploration at its finest. No more then 48 hours after everyone left out for the summer, I had a serious urge to get out exploring and grab some footage via my GoPro Hero+ and Canon T3i while doing it. I had woken up late in the day, taking advantage of the eerie silence that lay within my house that day and would continue for another 3 months. With no planning and 4 hours of daylight left to burn. I made a quick map research of the surrounding towns. Older is better I focused in on a old town that was not far from me. You know, one of those towns that if you blink its gone. What struck my interest is that a small creek disappeared more then what you expect it to disappear from the map. You know when a body of water gets covered when going under a road, there is a short distance (the width of the road) that it does not show up on the map. Well in this case it was much longer. I was suspicious that it was just a map error. Peering closely on the satellite imagery. Switching back and forth between Google and Bing’s birds eye view, I followed the creek as it winded down the slop and disappeared from view. I noticed that it disappeared into what looked like rocks. Yes, it seemed to be a hole surrounded by rocks. Not like a typical conduit style tunnel you see in newer tunnel construction. While the outfall of that tunnel was concrete conduit the intake was not. I thought it was worth the quick trip to check it out. Coffee to go, minimal gear, my newly acquired hard hat and I was out the door in a flash.

As I was nearing the area where this tunnel lays, I was paying close attention to the creek that would lead up to the inflow of the tunnel. Difficulties in visualizing the mouth was evident as the summer brush had already grown thick. Moving along the road at half the speed limit, I caught a glimpse at what looked like a hole surrounded by rocks. How could I of not seen this before. I mean I guess you really have to look and most of the time. Underground creek crossing under the road are non-remarkable. I pull up to where I am going to park. Convenient parking and all, directly across from the trail that I would be accessing the creek, this is just great. I traverse down the trail, past an abandoned house that sits on the creek, its like an whole playground here. Will definitely have to make a follow up trip granted its only 3 minutes from my house. How convenient.

I manage to cross the stream without eating too much mud and suddenly I am out in the clear. I am hunkered down for a few minutes as there is a walking trail that sits at elevation and I am down below at the creek. Its not like I am doing something wrong but people will get suspicious for anything in a small town. Coast is clear, I start rocking and rolling towards the entrance of a modern day conduit. I am suprised how large this conduit is granted the creek is really not that big. The sides of the creek show debris that sits a meter, a meter and a half higher then daily flow so I guess the 10 x 15 foot conduit is with good reason. Taking note of the graffiti free walls. Not long after I penetrate the tunnel, I can see that the modern conduit connects with an older section. There is a brick arch that wraps down meeting stone walls. When I get to this point, the tunnel almost veers to the right and I am struck dead in the face by an old bared window. A window I said, an underground window built right into the ceiling of the tunnel. There are moments of concern that I should ease up at shining my torch at the window, in case the residents would see me but I am intrigue at this thing. Peering further down into the tunnel it resembles an old mine. Wood timbers line the walls, the walls consist of hand laid stone. Smaller tunnels and cavities open up into the main tunnel which strikes me as century old storm drains. The brick arched ceiling convex, most likely where the road is. I can almost here the cars driving over top of it. There is one section that shows great wear and tear. Its where the modern conduit connects with the century old arched brick. A quick risk assessment concludes this is the most dangerous part of this tunnel, as it shows great instability, and my hard hat has already paid for itself. This is all just so wild.




During all this, I am seeing these huge insects flying around that there. By no exaggeration, these insects are as big as a small bird. I get this sense that, its like another world back in there past the old forgotten window. There is a slight haze back in there but a steady stream of venture driven tunnel breath is blowing into my face and I think little of these monster insects and begin setting up my Canon T3i for some exposure shots. Exposure shots really put you in the heart of a scenario. You literally have to stand there next to the tripod and wait and wait and wait. Usually your senses are heightened, so its like I can hear something that I cant make out what it is. At one point I am sure its music, almost music box like. Another moment it sounds like laughter. I presume that the water lapping over the stones some how has created a laughter. The tunnel is laughing at me. I am fairly tripped out. I am not the type of explorer that enters these tunnels in search of haunted grounds. Out of all the sites I have explored, haunted and evilness is just not what I look for or expect.

Anyways, once this lengthy process of setting up for x10-15 , 30 second exposures, trying my hand at different aperture settings, is finished, I continue on with the idea that I will make it to the end of the tunnel. That is where the water dumps down into the tunnel. At this point the water is about 8 inches deep. I am suddenly overwhelmed by swarms of gnat like insects. They are attracted to my light and have literally engulfed my head. I shrug it off, swatting away. During all this those huge flying insects are flying circles around me, only momentarily visible in my lamps but completely audible as their massive wings are vibrating the air. Submerged stones make the trek futher treacherous. Just as I get to the point where a wooden beam stretches across the tunnel width, I cannot take it anymore. The gnats are so heavy they are going up in my nose, mouth and ears. My senses are literally inundated and its almost all reflex at this point. Combining the blanketing swarm, with the massive flying insects, entering my no fly zones. I decide to abort. I high tail it out of there, disregarding eloquent foot placement and just slosh my way out. The swarm lessened the nearer I drew closer to the entrance.




Due to its accessibility, subsequent explorations were had here. One of them focusing one the old storm drain that was accessed via a modern 92 inch concrete pipe. No more then 20 meters into this pipe you enter an original storm drain that is built from rock. Heavy repairs are evident in the ceilings and notably what looks to be a plug in the wall. The explorer did not venture further then 10-15 meters deep into this section. Partly due to this exploration being done solo / without a buddy system and also because with further survey of the area, this old storm drain leads no further then a dead end with a metal grate 50 meters away on the side of the road.

With further research and surveying the area, I have pinpointed exactly what house is built into the tunnel. I would love to speak with the owner to get a view of the window from the inside looking out but until then. The window will remain a mystery, and will hopefully be preserved for future generations to view. As its truly a unique gem buried within the rocks.




Hendrick’s Folly : Old Guilford Avenue Diversion Tunnel



Jones Falls Conduit Old tunnel


After leaving the Goliath Chamber : Junction Chamber II , the explorer enters into an ancient like vestibule, only seen by few.  A passage into another outset, a unseen threshold of buried time . It is as symbolic as it is literal. Because at this point of the journey, you have crossed into the original, old Guilford Avenue Diversion Tunnel.

Upon entering Hendricks Folly, the air quality almost immediately changes. Almost like 2 distinct different atmospheres or gradients. Pockets of old, un-circulated air back in there. The explorer would push forward with much caution, as the air becomes thick, heavy and humidity laden. The explorer is concerned about this. It is assessed to be old air, stagnant air. The explorer continues to carefully assess the conditions. The mission could be aborted at any time. The density of the air in this section is evident when using flash photography.
jf conduit old hendricksProceeding forward, the tunnel landscape takes a drastic change. The floor is convex and brick laden, laid hundreds of years ago. For the first time, the explorer is one with the river. They walk in the river and not separate from it like the previous sections. The brick floor, is extremely slippery and the explorer ends up embracing the river, walking straight down the center. There is too much risk and energy expended by attempting to creep the sides of the sewer. The explorer finds that convex shape of the floor coupled with the ultra slick surface is difficult to remain up right. Water is leaking from the ceilings but the drops go unheard over the resonance of the rivers hum.

 

 

“The heading of the tunnel,under Guilford avenue, has been extended from the entrance of the retaining wall between Biddle and Chase streets to a point 25o feet beyond Preston street a total distance of 8oo feet” (ref. 1)

Approximately 100 meters deep inside this section, there is a massive storm drain outfall that draining a number of large buried streams into the diversion tunnel. It is always pushing out a high volume of air. A drain within a drain. The internal outfall tube is concrete with a brick laden bottom . After some research, it is concluded that this is “Jenkins Run”. Which means this massive tunnel leads into another network of century old storm sewers. In fact, as of 1909, it was draining 900 acres of area. Another excerpt from the Sewerage Commission of Baltimore City Report dated 1912 page 12 states:

“The heading of the Jenkins tunnel has been extended through to meet the large tunnel a distance of 430 feet The rock excavated from this tunnel is being crushed and used to form the concrete conduits in the bed of the Falls below Preston street”.

Jenkins Run Storm Sewer – AVOID remains with us and reminds us of the ideal plan of action.

As soon as the explorer navigates past this massive outflow,  a strong wind is pressing on their back. Again, this is a comfort to the explorer. In contrast with the previous stagnant air pocket, this fast moving stream of air enables further penetration.  Travel past this point continues to prove slow and strenuous. The sides of the tunnel remain convexed and angled upward. What feels like an eternity, the tunnel continues straight forward. Eventually, a slight bearing to the left is noted which obscures an possibility to assess what lies ahead. The tunnel wind begins to fade. After some time, the distant sound of rushing water is heard. The explorer is apprehensive in what lies ahead as the LED’s of the explorers lamps are only piercing the darkness so far. The tunnel finally straightens out again. The explorer finds themselves in the precursors of the Original Jones Falls Conduit…Jonesy’s Last and Final Run.

Guilford Avenue Junction : Goliath Chamber



Jones Falls Conduit - Goliath Chamber



Approximately 800-1000 meters, deep inside this stormsewer, lies a transition point from new to old. Its massive so some people always called it the Goliath Chamber. It is the Junction Chamber that converges the 2 1959’s built tunnels into 1 tunnel. The ceiling of the sewer increases in height furthermore. Its the largest chamber in the entire subterranean system. It is simply massive. The light from torches will be swallowed. Its that big. A century old jewel, buried deep under the city, with its citizens completely unaware of its existence beneath their feet.

JFX Diversion Tunnels


| Upper Jones Falls Conduits: JFX Diversion Tunnel |

Build Dates: 1959
Features: Massive 9.1m H x 7.6m W (30’x 25′) Modern 50’s build construction,
Proceeding past Junction Chamber 1, Triple Barrel Hall , the 3 intake conduits converge into 2 massive hallway like tunnels,running in parallel. Again these conduits composition are made up of concrete all the way around and are mistakenly referred to as the Jones Falls Conduits. The daily flow of the Jones Falls river runs through the western conduit, while the eastern conduit usually host a small stream of water being fed by 2 underground streams that outfall in here. Immediately after Triple Barrel Hall the tunnels bear slightly the right before straitening out again. While these tunnels do not run at depth, the enormous size of these underground tunnels are remarkable. More like underground sanatoriums. Like massive, never ending hallways.

Features:






Two conduits run in parallel under a major highway and eventually run out in front of a major Train station, which can be heard at times. Modern concrete construction, rectangular shape, that do no sit deep within the ground. Eastern tunnel serves as an outfall for 2 large lateral drains, one with a known SSO/CSO relief point. The N. Charles Street Storm Sewer & the Lovegrove Alley Storm Sewer. Tunnel Section length after Junction Chamber #1 1000 meters.

There are 2 large drains and a number of small drains that are positioned in the upper portion of the walls, towards the top of the ceiling. The 2 of the larger outfalls, are the Charles Street Sewer and Lovegrove Alley Sewer. They serve as combined sewer overflow outlets (SSO/CSO) and appear to have the capacity of 700 – 1000 cubic foot a second drains.

1202 said to “KEEP GOING” so we kept going

There is some notable graffiti art towards the end of this tunnel. One of the most impressive graffiti in the entire tunnel lies at the end of this section. Impressive due to the fact that it spans almost the entire face of the wall. Further research brings to light this style of graffiti is known as “Blockbuster graffiti” or “Roller Graffiti”. Its a massive piece of art with a hand holding a bottle, tagged by 1202 that reads “KEEP GOING —>” .

JFX Triple Barrel Junction Chamber | Triple Barrel Hall



It is at this point where the infall tunnel conduits go from 3 tunnel conduits into 2 massive tunnel conduits. The transition point involves a significant increase in the grade. There is an almost terrorizing like roar, a prominent change in acoustics can be heard ahead, as the now buried Jones Falls river quickly drops further in elevation and in turn increases its speed.

look down nares to triple
Looking South, tunnel floor grade increases, dropping elevation and ceiling starts to open up. Protective cast iron convex can be seen on the center dividing wall.





The junction point where the tunnel transitions from 3 tunnels to 2 tunnel the floor levels out. (Its difficult to describe this part in writing) but at this point, that is before the 2 tunnels are separate from each other (forming the main JFX Jones Falls River Diversion Tunnels), there is a brief opening of the western side and the eastern side. The opening is approximately 4-5 meters long with a 20cm lip/curb that contains/separates the daily flow of the river from the eastern flood conduit. The Jones Falls river is running at velocity in the western conduit as the steep grade levels out. Both conduits bear west and past this point you are separated from the main/daily flow of the river.

Looking North – the left conduit is the western conduit containing the daily flow. The center and right conduits convert into one conduit which serves its purpose during flood stage.

The beginning of the central dividing wall, in which divides the 2 tunnels, has a heavy protective convex piece of cast iron encapsulating its face. The dividing wall itself appears to be approximately 20-25 centimeters in thickness and serves as a protective piece of the design.
