Recovery: On 02/09/1998, Global Occult Coalition operatives 
carried out a raid on a Chaos Insurgency facility several kilometers 
north of Dellmarsh, Maine. Foundation agents in the area were 
acting as escorts to the GOC convoy. The raid was successful, with 
no critical GOC casualties. 


Several anomalous items were recovered by the GOC, including 
[REDACTED]. Also among the recovered items was an 
interdimensional portal (tentatively designated SCP- __pre-recovery) 
being operated by the Chaos Insurgency as a means of 
communicating with SCP-2173-1, with the suspected intentions of 
securing anomalous weaponry. 


As the convoy approached Dellmarsh, an ambush by the remnants 
of the Chaos Insurgency garrison destroyed several GOC vehicles 
using anti-tank weaponry, including the cargo truck carrying SCP- 
Whether the destruction of this item was intentional is unknown at 
this time. When the item was destroyed, the area designated 
SCP-2173 was quickly enveloped by its current atmosphere. 
Foundation assets and local emergency responders carried out 


evacuation procedures while better-equipped Foundation assets 
mobilized to contain the anomaly. The GOC has been informed of 
the fate of their agents, but all further information regarding 
SCP-2173 has been kept within the Foundation to limit 
complications to diplomacy with SCP-2173-1.

Exploration Logs 
+Summarized Initial Exploration Log 


Foreword: On 02/12/1998, 72 hours after preliminary 
identification and containment of the anomaly, eight 
operatives trained as Hazardous Materials technicians, 
equipped with Level A hazardous material protective 
gear, supplied air breathing apparatus, and helmet- 
mounted radios, were authorized to carry out 
investigative and possible rescue operations within 
SCP-2173. 


Manned Exploration 01, carried out by a two- 
man team (Team Alpha), with an additional 
two-man Rapid Intervention Team on standby. 


Additional Notes: Plans had initially anticipated 
further exploration, necessitating four 
additional operatives (Team and RIT! Bravo). 


Results: At 13:15 local time, approximately five 
minutes after entering the anomaly, Team 
Alpha reported a suit breach and requested 
immediate extraction. RIT Alpha entered the 
anomaly in a rescue attempt for Team Alpha. 
At approximately 13:23, RIT Alpha Leader and 
RIT Alpha 2 exited the anomaly, carrying 
Alpha 2 and Alpha Leader, respectively. All 
four operatives showed symptoms of acute 
chlorine exposure; symptoms were more 
severe in Alpha Leader and Alpha 2. All four 


operatives were successfully decontaminated 
and treated. No breaches were found in any of 
the operatives’ protective gear. 


As a result of the near-loss of two high-value 
Foundation operatives, all further exploration 
of this anomaly is to be carried out robotically. 


-Site Director 
+Summarized Robotic Exploration Logs 


Foreword: On 02/14/1998, 48 hours after initial 
exploration, six standard electric tracked probes and four 
standard electric aerial exploratory probes were sent to 
Provisional Site 2173 in order to verify and expand on 
the initial exploration team's findings. 


Robotic Exploration 01, carried out via 
tracked Probe 2173-01 on 02/14/1998 


Additional Notes: Probe 2173-01 was outfitted 
with two atmospheric chemical composition 
sensors. In order to verify the effects 
encountered during initial exploration, one was 
hermetically sealed within an atmosphere with 
composition identical to the area outside the 
anomaly. 


Results: Within five minutes, the atmospheric 
composition within the hermetically sealed 
container was identical to that within the rest of 
the anomaly, providing strong evidence that 
this was the cause of the initial exploration 
team's chlorine exposure. 


Robotic Exploration 05, carried out via 
Tracked Probe 2173-02 on 2/15/1998 


Additional Notes: Probe 2173-02 was 
equipped with infrared, ultraviolet, and visible 


spectrum monitoring equipment. Purpose of 
exploration was to identify a source of the 
anomaly. 


Results: Robotic probe followed same path as 
manned exploration team. Further 
investigation revealed several dead bodies, 
many unarmed, suspected of being civilians. 
Several damaged vehicles, both GOC and 
civilian, were also identified. A limited number 
of documents were recovered from easily- 
accessed GOC vehicles. 


Robotic Exploration 11, carried out via Aerial 
Probe 2173-01 on 2/16/1998 


Additional Notes: This was the first successful 
aerial exploration of SCP-2173, carried out 
after several technical delays. Probe was 
equipped with infrared imaging equipment. 


Results: Several GOC vehicles were identified, 
along with several armed corpses considered 
unlikely to be civilians. Armaments identified 
included RPGs and similar anti-tank weaponry, 
high-caliber sniper rifles, and assault rifles. 
Evidence of a firefight was found in the city 
center, along with an area of significantly lower 
temperatures (approximately 5°C less than the 
surrounding area) centered on the remains of 
a shipping container with GOC markings.2 


Robotic Exploration 26, carried out via Aerial 
Probe 2173-03 on 2/28/1998 


Additional Notes: This and the majority of all 
further aerial explorations of SCP-2173 were 
carried out at 1-week intervals, as per the 
then-newly established Special Containment 
Procedures. 


Results: Several anomalies not previously 
observed in SCP-2173 were observed during 
Exploration 26. Anomalies included several 
structures not previously existent within 
Dellmarsh that appeared to be constructed of 
canvas or similar temporary building 
materials3. Anomalies also included the first 
observations of SCP-2173-1, which appeared 
to be wearing equivalents to pressurized 
Hazardous Materials protective gear. 


Robotic Exploration 27, carried out via 
Tracked Probe 2173-07 on 2/28/1998 


Additional Notes: Exploration 27 was carried 
out three hours after Exploration 26, upon 
being approved by Site Director in order 
to investigate the new developments within 
SCP-2173. Tracked Probe 2173-07 was 
equipped with infrared, ultraviolet, and visible 
spectrum monitoring equipment. 


Results: Probe 2173-07 successfully identified 
several new structures within SCP-2173, 
including what appeared to be an armory/ 
central supply depot, before connection was 
lost. Final video feed from probe indicated that 
the probe was damaged or destroyed by an 
instance of SCP-2173-1 via unknown 
armaments. 


In order to maintain brevity of this document, all further exploration 
logs have been redacted, with a timeline summarizing results of 
major events enclosed. 


+Timeline of Events Regarding SCP-2173 


* 03/10/1998: Digital Chaos Insurgency documents 
recovered from SCP-2173 were decrypted, 
resulting in understanding of the Chaos 
Insurgency's methods of communicating with 


SCP-2173-1. Contact between Foundation and 
SCP-2173-1 was established. 

05/03/1998: SCP-2173-1-built structures of a 
seemingly more permanent nature than those 
discovered during Robotic Exploration 26 were 
discovered. Communication with SCP-2173-1 
confirms that structures were part of a project to 
build a permanent Forward Operating Base within 
SCP-2173. SCP-2173-1 instances were observed 
for first time not wearing HAZMAT-equivalent 
protective clothing. 

05/12/1998: Intercepted SCP-2173-1 
communication indicates possible knowledge on 
the part of SCP-2173-1 of discrepancy between 
the SCP Foundation and Chaos Insurgency, and 
continued communication and cooperation 
between SCP-2173-1 and the Chaos Insurgency. 
05/27/1998: Continued SCP-2173-1 cooperation 
with Chaos Insurgency was confirmed. 
06/03/1998: Objects seemingly similar in function 
to artillery, guided missile systems, and radar 
equipment were observed along the perimeter of 
SCP-2173-1's FOB. Negotiations to encourage 
disarmament and cessation of cooperation with 
Chaos Insurgency were initiated. 

06/04/1998: Provisional Site 2173 was 
redesignated Containment Site 2173. 
06/10/1998: Foundation surface-to-surface and 
air-to-surface missile systems, along with 
Foundation orbital, artillery, and naval assets were 
put on standby in order to destroy armaments 
within SCP-2173 if necessary. 

06/17/1998: Negotiations with SCP-2173-1 were 
concluded. Terms of negotiations can be found in 
document 2173-1a. Foundation assets were 
ordered to stand down. 

07/03/1998: The majority of SCP-2173-1 
constructs on the border of the FOB were 
observed as having been dismantled, the 
exception being several objects similar in 


appearance to infantry-deployed mortars and 
mobile radar dishes. 

07/04/1998: Several distressed communiques 
from SCP-2173-1 indicate alarm at Containment 
Site 2173's 4th of July preparations. It is unknown 
at this time how SCP-2173-1 was able to observe 
these preparations. The celebration was cancelled. 
Emergency aerial exploration of SCP-2173 
revealed that SCP-2173-1 had been re-arming 
several previously disassembled artillery units. 
07/19/1998: Several loud explosions were heard 
from within SCP-2173. The preceding and 
following communication with SCP-2173-1 is 
evasive as to the nature of explosions. 
07/21-08/31/1998: Sounds reminiscent of heavy 
construction equipment were heard sporadically 
from within SCP-2173. The noises matched no 
known brands or makes of construction 
equipment. 

09/01/1998: The sounds of construction equipment 
from within SCP-2173 ceased. The final sound 
was recorded at 00:19 local time. 

09/03/1998: Scheduled monthly aerial exploration 
revealed that several pre-existing structures within 
SCP-2173 had been demolished, with buildings 
matching SCP-2173-1's architecture having been 
constructed to replace many. New structures 
include what appears to be a permanent barracks 
and mess hall, and a permanent armory. One area 
was confirmed through later explorations as having 
been converted into an outdoor marksmanship 
range. 

11/03/1998: Several instances of SCP-2173-1 
were seen with digging tools and other unidentified 
equipment digging and refilling small (less than 1m 
deep) trenches approximately 80 meters outside 
the border of their FOB. 

11/04/1998: Several tracked Basic Observation 
Probes (designed for discreet reconnaisance for 
Armed Mobile Task Forces) modified to work 


within SCP-21 73's environment identified the 
trench line as being a minefield designed to 
destroy heavier tracked probes. 

12/03/1998: Aerial Probe 2173-05 was destroyed 
by a small anti-aircraft missile system as it 
approached SCP-2173-1's FOB. Foundation long- 
range weapons systems were brought back on 
standby. 

12/05/1998: Negotiations regarding disarmament 
were resumed. 

12/11/1998: Negotiations were concluded. Majority 
of Foundation long-range weapons systems were 
ordered to stand down. 

06/02/1999: Several computer systems, both 
civilian and Foundation, within 50km of SCP-2173 
crashed simultaneously. Similar problems were 
reported by SCP-2173-1, with accusation towards 
the Foundation featuring prominently in most 
received messages. Amnestics were applied to the 
local population via aerosol as necessary. 
06/03/1999: Aerial exploration revealed several 
remaining SCP-2173-1 weapon systems in a non- 
ready state. Intercepted communication revealed 
that several weapons systems affected by the 
mass malfunction the previous day were still 
experiencing computer issues. 

08/03/1999: Aerial exploration revealed significant 
SCP-2173-1 expansion since the previous 
exploration before the probe is destroyed. FOB 
borders had expanded to within 30 meters of the 
minefield. Several artillery and missile systems 
were observed, many in types not previously 
observed, and in greater numbers than previously 
observed. Foundation long-range weapons assets 
were brought back online.

control, which retreated up a nearby tree. 

Control Test B: Subject cowered in the corner as far from the control 
as possible. Control took no notice of subject. 

Results: Subject ran toward SCP-247, barking loudly. At 
approximately five (5) meters away subject slowed to a halt and 
became silent. At this point, SCP-247 rolled over and made a 
‘mewing’ sound believed to be a sign of annoyance. The subject 
retreated to a far corner of the enclosure with its tail between its 
legs. 

Notes: That was extremely odd. Further testing recommended. -

Experiment Log 247a-02i-ii 

Date: / /2010 

Test Subject: A male tabby kitten with the same apparent age as 
SCP-247. 

Control Test A: Subject played with the control in the manner 
expected of kittens. 

Control Test B: Subject climbed a tree and attempted to hide itself 
from the control, displaying visible signs of terror. 

Results (test i): Subject approached SCP-247 and mewed. SCP-247 
responded in kind and played with the tabby kitten. The resulting 
footage is extremely odd; at one point SCP-247 lifts the subject 
(which appears to be the same size as SCP-247) with a single 
forepaw, while at another point SCP-247 lifts the subject with its 
mouth, clearly showing that its mouth is much larger than it appears 
to be. The leading researcher characterized this as adorable but 
remarked that it gave him “a headache.” Due to a faulty recorder, 
this test had to be repeated. 

Results (test ii): Subject approached SCP-247 as above. SCP-247 
made a deep purring sound, analogous to a growl. Subject reacted 
as in control test B. 

Notes: This seems to indicate 247 has some degree of conscious 
control over its apparent appearance. - Researcher S

SECURITY CLEARANCE 
VERIFIED 


All data regarding Incident 2173-12 has been expunged 
from the records, besides this version of this document. 
If you're reading this, you have personally been selected 
by the O5 Council to be a member of a recently formed 
Task Force. Task Force lota-77 has been formed to 
investigate, attempt contact with, and possibly neutralize 
the anomalous entities known as "Pattern Screamers." 
As of right now, we have no idea what they are. Our only 
source of knowledge of them comes from glitches, 
errors, and general fuck-ups that keep happening in the 
records, and messages sent from SCP-1795. 

Not just our records, either. All records. Every digital 
network on the planet that we've tested shows evidence 
of infiltration. We don't know how they've done it. At first, 
we thought it was just the Foundation's databases, and 
that it might be some sort of spyware or computer virus. 
Then we found records in the ruins of Prometheus Labs 
that detailed the same entities, but showing up in literary 
works. Then we ran a sweep. The source code of almost 
every digital SCP contains messages from them, as do 
hundreds of mistyped pieces of literature and nonfiction 
works, both anomalous and otherwise. 

No, don't worry. The patterns from these things are 
buried so deep, it would take someone with as many 
resources as us to find them, and we're using computer 
programs to monitor every organization that does, 
looking for mentions. And no, there's no one besides you 
and the others we've selected who know about this. If 
something comes up, you'll get a message over the 
Foundation ethernet. You'll know it when you see it, and 
no one else will. You'll carry on with your current 
assignment, but you'll carry out your new functions, too. 
If your new job starts to get in the way, we'll sort it out. 
God help us all, and Godspeed.
