Risk Class:

Special Containment Procedures: The 15 km by 15 km region containing the entrance SCP-5830 is to be staffed by no fewer than twenty armed guards at all times carrying 12 gauge shotguns, stationed across the area to monitor any and all attempted breaches, while also maintaining sufficient distance from the entrance to SCP-5830 to not allude to its location. Admittance to the surrounding Northeast Greenland National Park is to be restricted to this end.

Access to SCP-5830 is to be restricted to personnel with security clearance level 4 or higher, and is to be mediated by no fewer than one armed guard and precisely two personnel cleared to navigate SCP-5830. Due to the temporal anomalies present in SCP-5830, exploration attempts are to be limited to three days in length.

The nearby research station of Daneborg is to be monitored for any attempts to explore northward toward SCP-5830; such attempts should be initially deterred and terminated if necessary. To this end, an anonymous outpost is to be erected in or near Daneborg. During the summer, similar procedures are to be enacted to deny access the area surrounding SCP-5830 via Zackenberg station1. Any person(s) which successfully enter SCP-5830 must be tracked and either detained, terminated, or verified dead by local personnel. Wildlife is to be also kept from entering SCP-5830.

Any objects or person(s) which attempt to exit SCP-5830 are to be immediately detained if not authorized, or terminated should they present immediate and effective hazard to site personnel or civilians. All objects found within SCP-5830 are to be recorded for Foundation review.

Description: SCP-5830 is a large glacial cave located at 7█°██’ N, 2█°██’ W along the eastern coast of Greenland. Its entrance is located beneath approximately 62 m of ice along a narrow inlet of the Arctic Ocean, being roughly semicircular with a diameter of 19 m. Meltwater from the glacier regularly runs through SCP-5830, though attempts to trace the water's flow via dissolved dyes and buoyant tracking devices have been unable to determine any point of exit. The entirety of SCP-5830 also seems immune to calving, and changes only minimally in size and relative integrity with seasonal periods of melting and freezing.

When entered, SCP-5830 continues to resemble a glacial cave, with an upper dome-like wall composed entirely of ice containing fragments of dust and rock, and floor made of a brown-black mixture of gravel and silt. The temperature within SCP-5830 consistently measures -2°C, with little variation due to external temperature or depth within the cave. The initial cavern (called Depth 0 for navigational purposes) of SCP-5830 extends downward beneath the glacier, arriving at a depth of 17 m before branching into two tunnels which diverge at an angle of 120° (each of which is Depth 1).


Entrance to and initial branch of SCP-5830.

Each branch strongly resembles the initial cavern in size and shape, making navigation of SCP-5830 rather challenging (see Document SCP-5830-A for navigation procedures). Proceeding down either of the two branches will lead to another branch point, which again splits into two tunnels of identical size and shape; each branch then leads to another two branches, which lead to another two, and so on. Exploration attempts have confirmed the existence of all Depth 9 branches, with the furthest exploration of any single path arriving at a point at Depth 57; despite this nomenclature, however, branches of equal Depth may not be located at the same distance below sea level, with some paths actually rising above the initial cavern in altitude. The total area spanned by SCP-5830 is at least 24,000 sq. km., and the maximum recorded depth is ████ m below sea level.

There exist at least seventeen paths within SCP-5830 which, amazingly, terminate; these termination points are designated SCP-5830-1, and appear as large, circular caverns measuring 10-20 m in diameter. No further tunnels or crevices extend from these caverns, and meltwater which would accumulate at these points appears to completely seep into the gravel and silt floor, unable to be traced. It also appears time does not pass within the confines of SCP-5830-1, at least not in the usual sense; instruments which rely on mechanical or natural means to determine the passing of time stand still, and attempts at radio communication to external sources fail. Personnel who enter SCP-5830-1, however, are able to keep time by counting aloud, tapping, or other similar means.

Among the known instances of SCP-5830-1, seven are entirely empty and devoid of any further anomaly or artifact. The ten remaining termination points, however, contain instances of SCP-5830-2: replicas of other known SCP objects completely frozen in time and space. Each instance of SCP-5830-2 is visually indistinguishable from the anomaly which they emulate; composition, texture, radiation signatures, and even odor are furthermore identical. Attempts to interact with or stimulate response from instances of SCP-5830-2 yield no results, and specific experimentation for each instance is detail below. Each instance of SCP-5830-2 cannot be removed from the SCP-5830-1 cavern which contains it and indeed cannot be moved or relocated within the cavern by any means.

Navigation: LLL█████
Depth: 8
Contains: empty

Many personnel who have studied SCP-5830 suspect that more instances of SCP-5830-1 and SCP-5830-2 can be found within the caverns, and some have conjectured that all known and unknown anomalous objects possess an emulation within SCP-5830 (though current investigations provide little support for this hypothesis, and if it were true such objects would necessarily be located at extremely great Depths).

At this time, the complete inertness of instances of SCP-5830-2 cannot be fully verified. Ongoing experiments have inferred amounts of anomalous activity prior to discovery to SCP-5830 in the majority of instances.

Discovery: SCP-5830 was first discovered on ██/██/20██ by Dr. Hans Knudsen and Dr. Daniel Moorhouse, both climate scientists working from ██████████ University (as visiting and associate professors, respectively) to measure ice sheet melting and calving in the far northeast of Greenland. Both Knudsen and Moorhouse joined an expedition with five additional researchers and a handful of crew from the village of Daneborg north to begin their research; nine days later, only Knudsen and four others returned. The bodies of two researchers were found near the entrance to SCP-5830 under collapsed ice. Moorhouse & a Tunumiit Inuit man were found dead in SCP-5830-1-3, with Moorhouse lain against the body of SCP-5830-2-1; Moorhouse's journal was recovered from the corpse, and a transcript of the relevant legible pages is contained in Transcript 5830-B.

Addendum 0.1: Eight days after the discovery of SCP-5830, a woman suffering severe frostbite and malnutrition stormed the Daneborg airstrip during the boarding of a Danish military biplane. Dr. Knudsen, one of the passengers, was attacked by the woman, receiving minor lacerations to his left arm and shoulder before the woman was killed by Danish military personnel. The autopsy report of this woman can be found in Report 5830-E.

Following this incident, Dr. Knudsen committed suicide in a Swedish jail while awaiting trial.

Document 5830-A: Navigation Procedures

Approved on ██/██/20██ by Dr. Wainwright
On file at Site-███

Direction sheets will be given to navigators by personnel following a request by a Foundation researcher to enter SCP-5830 with an allotted time to be spent in SCP-5830. Once given directions by the appropriate personnel, immediately note its length and sequence of turns. Commit the length to memory, and say it aloud often if you must. Before departing, prepare a pack containing:

  • no less than three days worth of food, water, and cooking fuel
  • at least 60 m of coiled rope
  • a sleeping bag rated for at most 20°C
  • a tarp and four wooden stakes
  • no less than four emergency flares
  • two full rolls of reflective tape
  • a pocket knife or similar multitool
  • a progress log and a writing implement

When navigating SCP-5830, always take care to note what directions you've taken and which one you have left to take. Personnel have died lost within SCP-5830 far too often due to improper record-keeping, despite the best efforts of the Foundation to maintain a simple navigational infrastructure for its study.

At each branch point, find the first letter of your direction sheet not struck- or blackened-out; call out this direction to those in your party (L for left or R for right) and proceed in that direction. All branch points should have two strips of tape along some wall to identify the direction of the exit. If you encounter an unmarked branch point, act in your own accord and mark the branch with your tape.

Once you have entered the next branch, strike the letter from your direction sheet and prepare to repeat the procedure again. This amounts to progressing one Depth level into SCP-5830; the entrance is at Depth 0. No amount of mental tracking of distance or altitude can assist in orienting oneself; only the maintenance of the direction sheet and your Depth along it can guarantee survival.

Following the completion of the necessary research (most often at a terminus), begin navigating using the tape markings at each branch point to exit SCP-5830; do NOT attempt to move between two different locations within SCP-5830 without first exiting and re-entering the cavern.

If you have found yourself lost within SCP-5830, halt your exploration party and begin returning to the surface via the exit markings; do NOT attempt to determine and/or correct the point of error while within the cavern. If you have found yourself in a location without sufficient markings, do NOT attempt to navigate out by guesswork. Instead, drive a stake into the ground where you currently stand and tie a length of rope to it; walk in some direction while holding the rope until you either a) arrive at exit markings, at which point you may proceed to escape SCP-5830 or b) exhaust the rope. Backtrack along the rope and attempt a different path.

If, even after exhausting all escape routes within your rope's allowance, you are still unable to exit SCP-5830, set up a small outpost to survive until location personnel are sent to find you and your party. In the event of injury or death, be sure to write as many details as possible about the event in your personal log. If you encounter any previously undocumented anomalous component of SCP-5830, including but not limited to an instance of SCP-5830-1 or SCP-5830-2, log its presence and location. Do not engage with any wildlife or other entities encountered in SCP-5830.

Transcript 5830-B: Personal Journal of Dr. Daniel Moorhouse

Jun 15, 20██

Knudsen's gone off north to check logs from the weather station. I planned to join him, of course, but I couldn't deny my inner spelunker a chance like this. This glacial cave is quite large and doesn't seem to have been impacted too bad from the recent heat wave. A real treat.

We've agreed to meet back up at the cave entrance tomorrow morning. Erica and Kuupik have joined me as well, which is nice. Kuupik's always been quiet so maybe I'll get the chance to talk with him a bit more; he's lived in Tasiilaq his whole life and knows the land better than anyone. His English isn't great, though, but who can blame him? Guy's always got a stoic look to him too. And Erica, well, she's the polar opposite most of the time. Been quiet today, though.

It's actually a bit warmer in here than I would've expected. Ice is a good insulator and all but the warmth is almost unnatural. Might be due to geothermic activity. I'll ask Knudsen if Zackenberg picked up on anything seismic.

To be frank, I am a bit disappointed I couldn't convince him to join us. Apparently being ahead of schedule isn't enough to justify popping off into a cave for the day. To each his own. He insisted I enjoy the day.

Jun 15, 20██

We've set up a small camp about a mile into the cave. We've run into three different forks in the tunnels along the way. Pretty strange, actually, since a lot of the cave walls look very similar. If you took photos of three different spots and told me two of them of were the same I'd probably believe it. I would have guessed some more variation in the caverns and such, but I can't say that these "ice tubes" aren't cool either.

Interview Log 5830-C: Interview with Dr. Hans Knudsen

-Begin interview-
Dr. Wainwright: Dr. Knudsen.
Dr. Hans Knudsen: Yes.
Wainwright: How are you feeling?
Knudsen: Tired. Very tired.
Wainwright: Apologies, doctor. We'd like to tidy up this whole fiasco quickly, if you can understand.
Knudsen: Yes, of course.
Wainwright: Let's start from the beginning, then. When did you arr…
Knudsen: May 29th. We came from Tromsø, with another crew that stopped off in Reykjavik.
Wainwright: And who all were members of your crew?
Knudsen: It was Moorhouse's crew, really. He organized the expedition back in March.
Wainwright: And who…
Knudsen: Five research assistants from ██████████ University; two of them my students, three of them Moorhouse's. We had an additional three crew members from Zackenburg station, and one local from Daneborg to serve as a navigator and translator.
Wainwright: How do you know Dr. Moorhouse?
Knudsen: Professional colleague, though I've known him since graduate school. We both studied at ███████ College and went on to pursue academic positions in the States. He got a spot at ██████████, while I had to settle for a position in Sweden. We met up again when ██████████ invited me as a visiting professor. Nice guy, though a bit…pretentious at times.
Wainwright: You took up some students during this time. Who were they?
Knudsen: Erica Parsons and Alek Oltosky.
Wainwright: Do you know Moorhouse's students?
Knudsen: Yes, though not well. Kevin Zheng, David Carlisle, and Victoria… oh, I don't remember her last name.

There is a pause Knudsen continues to try to remember the name.

Wainwright: That's fine. Can you talk about what happened after arriving at Daneborg?
Knudsen: Yes. We made a small station just outside of Daneborg; the locals didn't really care for us but didn't mind us either. We told them what we were there to do through a man called Kuupik, and they lent us some supplies and a shotgun for polar bears.
Wainright: What were you there to do?
Knudsen: The original goal was to set up some weather stations up north to track warming over the next six months and collect some ice samples.
Wainwright: Your 'original' goal?
Knudsen: Well, we still succeeded in it, for the most part. Some of the stations got knocked out by a blizzard, but for the most part we did what we needed to do.
Wainwright: So why do you say…
Knudsen: Moorhouse insisted on some additional studies. We saw signs of massive calving in the area, and lots of glacial caves and alcoves and such. Moorhouse is a geologist at heart and was adamant that we dedicate at least a bit of our extra time to them.
Wainwright: Did you?
Knudsen: Yes, of course. Moorhouse led a few parties with Erica and David to examine some rock samples along the glacial cliffs. Erica's primary background is geology too, and I would guess David's as well. I kept the others for our usual operations.
Wainwright: How did Moorhouse come to arrive at…that cave?
Knudsen: We both spotted it on one of our last days out of Daneborg. We stopped by it to look around, and saw that it was rather large. We all took a look around the entrance, and Moorhouse said he'd love to spend a day or two here if it could be allowed. Erica agreed.
Wainwright: And I take it you obliged?
Knudsen: Yes. I asked Kuupik if he could join them in case they needed to navigate back to Daneborg on their own, and he agreed. The three of them set out and the rest of us went to secure the last weather station. We gave them from that morning until we returned the evening tomorrow. I think it was a bit of a non-professional adventure for them, too.
Wainwright: Did you want to join them?
Knudsen: Yes, a part of me did…more parts of me are glad that I didn't.

Knudsen's speech begins to sound more forced and creaky.

Wainwright: What happened when you returned to the cave?
Knudsen: We waited. We hoped they were making their way out. David insisted on looking in a bit farther to find them, or maybe a trace of them. Victoria followed him in, and Alek and Kevin and the rest of the crew and myself elected to stay outside. I told David before he went searching to call out to us every few minutes, and we'd call a reply. If we weren't in earshot, turn around.
Wainwright: Seems sensible.
Knudsen: It is if you obey it. They didn't. After half an hour, I called and received no reply. We tried six more times with no luck. None of us were about to do the same thing again and go in after David and Victoria, so we continued to wait.
Wainwright: For how long?
Knudsen: Three hours, until a blizzard began to roll in. We couldn't keep waiting around, and we weren't about to hole up in a cave and worry the crew back in Daneborg. We elected to trek out, and work to form a search party later when the weather was in our favor.
Wainwright: When did the search party set out?
Knudsen: The Sirius Patrol2 set out with their dog sleds two days ago. You and your crew showed up only five hours in.
Wainwright: Lucky that we did at all.
Knudsen: I suppose.

There is a pause as Wainwright reviews his recent notes.

Wainwright: Dr. Knudsen, if I might be so frank, I do believe your handling of the past three days is best described as 'careless'. We've only recovered corpses, after all.
Knudsen: Are you a police officer, Dr. Wainwright?
Wainwright: No. I do, however, have permission from authorities from the Danish government and Naalakkersuisut3 to conduct all sufficient methods of investigations during my time here. Four scientists and an Inuit tracker don't just die only miles from their station, especially with radio tracking available the entire time.
Knudsen: Not to be insolent, doctor, but our GPS capabilities were interrupted during the trip back to Daneborg. We probably hiked about five miles while off the grid.
Wainwright: Records from Zackenberg show otherwise.

Knudsen is silent, appears nervous

Wainwright: Doctor?

Knudsen attempts to run from the room, is immediately apprehended in the hallway.
