Trying to remember the hashtag for today.

#subterraneanSaturday?

A disused railway tunnel in #Derbyshire, part of the High Peak Trail. April 2014.

Curved stone wall, rectangular blocks neatly fitting together but with definite discontinuities, arcing up and over the camera's viewpoint - an old railway tunnel. Daylight intrudes from the right, reflected from damp areas on the stonework above, with green algae in drier areas.

Bonus #subterraneanSaturday - #longExposure view from the front (or was it the back?) of the automated train at #SeaTacAirport. Engage warp speed! From January 2018.

#airports #trains

View directly down the tunnel for an underground train, blurred by the train's movement into a central explosion of lines and angles.

For #subterraneanSaturday - some icy stalagmites deep inside #Raufarholshellir #LavaTube, #Iceland. (A 20 second exposure for this!) From August 2015.

#caves #ice #underground

Glistening white, curved and crystalline icy stalagmites emerging from angular, jagged, dark volcanic rocks.

#SubterraneanSaturday - the #monorail #tunnel beneath SeaTac airport, south of #Seattle. I'm pretty sure I've seen this exact place in at least one video game...

February 2013.

Dark, dingy and grimy concrete tunnel curving off into the distance - at the bottom is a monorail track and associated infrastructure, and to the left a raised walkway lit by fluorescent lighting. Wall and ceiling covered in narrow pipes. Taken from the front (or was it the rear?) of one of the driverless monorail trains, through the large window.

For #subterraneanSaturday - a large concrete corridor under a hillside (see a previous photo!), part of the old artillery bunkers overlooking the Golden Gate Bridge.

Golden Gate National Recreation Area, #SanFrancisco, February 2011.

#concrete #brutalism #dereliction #abandonedPlaces

Large rectangular corridor, walls and ceiling flat, weathered but almost glossy concrete - two dark metal gates hinged into alcoves, small ports along the walls and metal fictures on the ceiling. The far end is illuminated by evening sun - the light echoing along this underground corridor.

#SubterraneanSaturday - a near-monochrome #infrared shot of a #busker in an underground walkway. #Chicago, August 2010.

People walking through a wide, rectangular underground walkway with shiny tiled walls, central point perspective - near darkness, people sihouetted against glare from daylight at end of tunnel. Against one wall, near to the end of that tunnel - a seated man holds an object, perhaps a guitar, seemingly deep in concentration - he is a perfect dark cut-out against the bright wall behind him. Near-monochrome infrared photo.

Too early for #SubterraneanSaturday - so have an underground #fingerpostFriday instead - a rather steeply angled sign pointing towards Stromboli, deep beneath an volcanic, Icelandic landscape. Includes extra shots for context! August 2016.

#volcano #lavaTube #VatnshellirCave #Snæfellsjökull #Iceland

Damp, rough wooden sign pointing down and to the left, marked 'STROMBOLI 3591KM'. In front of a lumpy wall of volcanic rock, glistening in the light from a flashlight.

Tour guide in red jacket, hard hat, pointing at a large, rounded elephant's foot of long-solidified lava - scene illuminated only by a few flashlights, deep in an Icelandic lava tube.

Spiral metal staircase descending deeper still underground, in a huge, lumpy volcanic chamber - seen from beneath and one side, illuminated only by bright flashlights.

For #SubterraneanSaturday - an underground bunker in the old military fort at #Modlin, north of #Warsaw, #Poland.

I didn't have a good source of light with me, beyond an incredibly dim LED flashlight on my phone (this was September 2008) - so was slowly edging my way forward with the autofocus assist flash on my dSLR. After one or two corners - a doorway into utter, empty, cold darkness.

I ... decided to turn around.

#underground #dereliction #abandonedBuildings #abandonedPlaces

Entrance to an old bunker in a leafy green, wooded hillside - stained grey plaster with an empty doorway to one side, sturdy metal frame with an arched top, missing what would have been a small but incredibly sturdy door.

Immediately inside the bunker, a grey corridor with a curved, arched ceiling smoothly blending into the walls. Remnants of graffiti scratched on to the walls - a dark floor scattered with dead leaves. Thin streaks of water stains - scene is illuminated by a camera flash, floor in partial darkness from a shadow cast by the camera lens.

Further inside the bunker, looking through a grey doorway with an arched top. Thin streaks of water stains down the walls - scene is illuminated by a camera flash. Through the doorway - another corridor, and another doorway beyond that.

Further still into the bunker - another doorway opening into utter, total darkness...

A rather belated #SubterraneanSaturday - #Raufarholshellir #LavaTube, #Iceland - August 2015.

h/t @BjornIdle @KaneG

Dark, rocky, vaguely cylindrical cave - a lava tube in Iceland. Floor angled upwards, covered in huge boulders - lit only by a large hole in the cave roof, an overcast sky and faint rain eerily bright in the darkness. A small, faint human figure walks by fallen rocks beneath the skylight, blurred slightly by motion and a long camera exposure.

@KaneG
Gorgeous shot!

My own belated contribution to #SubterraneanSaturday - I do so love how old masonry reflects light in tunnels.

(Hopton Tunnel, #Derbyshire - a bit along the Cromford and High Peak Railway from Middleton - yes, there again. Definitely a lot less exploratory than yours - taken in April 2014 while walking the dog!)

View along a dark arched tunnel, dampness reflecting the distant daylight and bringing surface topography into sharp relief.

#SubterraneanSaturday

Missed yesterday as there were just too many choices, my procrastinating got the better of me.

So, here's the #WellTunnel in the #DetachedBastion at the #WesternHeights #Dover

An area high up on the#WhiteCliffs of Dover famous for it's #Napoleonic #Wartime structures.

Lit from the other end by my best friend, it's one of my personal favourites.

#SubterraneanSaturday

Bit out of the norm as you can actually visit this tunnel complex deep beneath #DoverCastle in #Kent. This is a photo of the #TelephoneExchange in the #CasemateLevel of the #tunnels. Rare to see it without the public tho. 😉

There are actually 5 levels, the staff say there are 3, and 1 hasn't been found.

A - #Annex - done
B - #Bastion - missing?
C - #Casemate - done
D - #DUMPY - done
E - #Esplanade - done (they say it doesn't exist lol.)

Will post more later on. 👍

A photo for #SubterraneanSaturday of a section of tunnel you can actually visit deep beneath #DoverCastle in #Kent. This is a photo of the #TelephoneExchange in the #Casemate #Level of the #tunnels. Rare to see it without the public.

Photo is of a wide section of concrete lined tunnel containing banks of old exchange machinery from WWII when these tunnels were used as a high security command centre deep within the chalk cliffs beneath Dover Castle.

A - Annexe was used as a military hospital/dressing station.

B - Bastion has 'officially' never been found, although I know where the entrance is supposed to be they won't grant permission to explore quoting everything from bubonic plague to mass war grave.

C - Casemate was a general staff area, communications, mapping rooms, officers quarters, even a BBC studio.

D - DUMPY or Deep Underground Military Position Yellow was a top secret bunker where even Churchill went to make plans for the allies and latterly converted to nuclear bomb proof allegedly.

E - Esplanade the castle rarely comment on, and at last attempt, still denied it even exists, it does I've explored all of it and have the pics to prove it.

#SilentSunday

Spent sitting by the Spoil Hole, (where the tunnelled chalk was dumped 80ft onto the beach) at Z Rocket underground shelter Nr. St. Margret's, Kent.

Loong way down and often inhabited by homicidal pigeons who will fly at you in an attempt to make you fall through it.

I said descend on leeeeeeft thud! 😜

#SilentSunday Photograph of figure sitting in a tunnel in front of a large hole in the chalk cliffs called a spoil hole, which is where all the tunnelled chalk (spoil) was dumped 80ft down onto the beach.

This is Z Rocket or more accurately St. Margret's 5.5" Underground Battery, which was a gun emplacement built to protect the Z Rocket Battery during WWII in Kent.

@doug

Perfect Doug, welcome to #SubterraneanSaturday :)

Anything underground is cool. Especially caves.

Line some up and next Saturday maybe post a few with the hashtag and see if we can find any other people with pics from underground. :)

Wow!

It appears my experiment with a #SubterraneanSaturday went much better than expected. 🙂

I had hoped that a handful of people would be interested in underground photography and exploring, maybe a dozen, but 62 favourite & 43 boosts (and climbing), in less than 24 hrs is incredible. 😎

Hopefully with all the boosts these posts will reach a much wider group of people and more pictures of what's beneath our feet may start appearing. 🤞

Thank you all for your interest. Much appreciated. 👍

#SubterraneanSaturday

Another one just for the lolz, this is an 18"/45cm #NapoleonicSewerPipe that connects the #SouthernCasemate to the #NorthernCasemate in #Dover near the #Citadel, later to become a detention centre for immigrants.

You literally have to have your arms above your head like a diver as you go in, and then scoot forward a few inches at a time with your toes pushing you.

People have said the thought of this size pipe makes them physically sick, I'm not surprised. :)

#Xplore

Picture of a pair of legs disappearing into an 18"/45cm Napoleonic sewer pipe that connects the Southern Casemate to the Northern Casemate, near the Citadel in Dover, Kent.

The pipe is set back into an arched alcove built of handmade Napoleonic bricks. I will post some photos of the other end of this route, where you emerge into what was the cesspit. :)

It's a very tight squeeze even for a slim person like me and is the only way of getting to the other side

#SubterraneanSaturday

Here's a shot from deep below #Middleton in #Derbyshire, it's an abandoned #LimestoneMine which can still be made operational if need be.

Where we were is approx. 200ft down, the workings span 25 miles over 3 levels, it's worked on the room and pillar method, with rooms 13 m wide and pillars 17 m square, ceiling height is 8 m.

It is immense, just for scale we have Westy lighting up the tunnel ahead.
