National Parks Service records do not show any purchases 
made by Foundation personnel within Yellowstone National 
Park, nor do they show purchases of permits or reservations 
of any kind by Foundation personnel. Purchases made by 
immediate family members of Foundation personnel are 
present, but at lower-than-expected numbers. 


¢ The internet browsing histories of all Foundation-owned 
computers have shown a complete lack of searches directly 
relating to Yellowstone National Park? (and, relative to search 
histories obtained from non-Foundation sources, a lack of 
searches tangentially relating to the park) prior to July 9, 2007. 

¢ The Foundation possesses no documentation that refers to 
Yellowstone National Park dated earlier than July 9, 2007. 


Interviewed personnel have either stated that they had no reason to 
pay attention to the area of the United States in which Yellowstone 
National Park is located, or could not recall what, if anything, was 
located in that area. Several were able to recall conversations or 
events in which Yellowstone National Park would most likely be 
mentioned, but was not. 


Yellowstone National Park itself is not believed to have any unusual 
properties, as several investigations have not detected unusual 
levels of anomalous activity in the park or its vicinity. Approval for 
Foundation personnel to visit the park during vacations is pending. 


Addendum 1422-1: SCP-1422 was discovered, and is believed to 
have been neutralized, on July 9, 2007 by Junior Researcher 
Scranton. JR Scranton had been asked to compile a report 
describing his experiences in SCP- 3; in it, he included a two- 
paragraph description of a family vacation to Yellowstone National 
Park. JR Scranton noted that he had not heard of the park prior to 
his entrance into SCP-__. This documentation was reviewed by Dr. 
Graff and Junior Researcher Halvorsen. 


When Dr. Graff performed a cursory search of relevant reference 
materials and discovered that Yellowstone National Park not only 
existed, but was world-famous and widely known, she sent an e-mail 
to Site 44's mailing list, asking personnel if they had heard of the 
park. When it became apparent that none had, Dr. Graff requested 
and obtained funding and personnel to investigate the anomaly 
further. 


Addendum 1422-2: Information on the cause of and exact nature of 
SCP-1422 is very limited. Several hypotheses relating to SCP-1422 
have been put forward: 


¢ SCP-1422 was caused by a separate probability-affecting 

anomaly, which may or may not have apparently unrelated 

properties. At time of writing, the Foundation does not 
possess the means to test this hypothesis. 

Yellowstone National Park did not exist prior to JR Scranton's 

exposure to SCP- __, after which reality was altered to 

incorporate the park. This may have been due to unidentified 
properties of SCP-__, any of the materials used in its testing, 
or JR Scranton. This behavior is not consistent with known 

information on SCP- __, and extensive testing has shown that 

JR Scranton and the materials used to test SCP- are not 

anomalous. 

* SCP-1422 has never prevented Foundation personnel from 
learning of Yellowstone National Park, but instead erased all 
memories of the park's existence upon their formation. If this 
is the case, research into SCP-868 may provide a method by 
which hypothetical anomalies similar to SCP-1422 could be 
counteracted. For the time being, however, this hypothesis is 
not actionable. 

* SCP-1422 was created by a conscious agency in order to 
conceal activity in or near Yellowstone National Park from the 
Foundation. Investigation into various groups and persons of 
interest has not shown conclusively that any individuals or 
organizations are capable of creating or using an anomaly 
such as SCP-1422; however, as this hypothetical individual or 
group could be expected to possess the means to prevent the 
Foundation from discovering them, this is not unexpected. 


Addendum 1422-3: 


Several personnel have rightly pointed out that 
SCP-1422 may not be truly neutralized, but simply 
operating in a different manner that we are unable to 
recognize; alternatively, numerous anomalies similar to 
SCP-1422 may exist, each tailored to specific locations, 
individuals, or even concepts. Indeed, if either of these 
were proven to be true, SCP-1422 would most likely 
qualify for Keter-ubique classification and heavily revised 
containment procedures. However, as SCP-1422 does 
not exhibit any observable anomalous properties (except 


those that no longer appear to be in effect), it is 
considered neutralized until proven otherwise.- Dr. Graff.

SCP-1423: Summer of '76 


Item #: SCP-1423 
Object Class: Safe 


Special Containment Procedures: SCP-1423 is to be contained in 
a standard containment locker, located in Site-77's Safe SCP 
wing. No personnel are to come into physical contact with 
SCP-1423, and any who have done so are to be treated as cognition 
hazard victims, and removed from active duty. Personnel assigned 
to research SCP-1423 are to be given full psychological evaluations 
every 4 weeks to detect if they have been affected. 


Description: SCP-1423 is a Polaroid photograph, circa 1976. It 
depicts several unidentified teenagers, and is believed to have been 
taken in the summer of that year. The message "We've had a great 
year, haven't we?" had been written on the back of SCP-1423 in 
charcoal. 


Whenever SCP-1423 is held by a human subject, they will suffer a 
memory altering effect. Over the next several weeks, the subject will 
show a tendency to reminisce about the last summer vacation they 
experienced in high school.’ Testing has shown these memories are 
accurate, and that SCP-1423 affected subjects have an unusually 
high rate of accuracy from these memories. 


SCP-1423 affected subjects will attempt to revisit locations from 
their vacation, such as concerts, cities, amusement parks, farms, 
hometowns, and will attempt to contact other subjects whom they 
contacted during that period. When revisiting these locations, 
subjects will express feelings of regret that they didn't experience as 
much as they could have. They may attempt to recreate the 
experience, however all subjects attempting to do so have reported 
immense dissatisfaction. 


Following this change, subjects will become highly possessive of 


SCP-1423, claiming that it documents their experiences. They will 
begin experiencing dreams of idealized versions of their vacation, 
which will increase in clarity the longer they possess SCP-1423. In 
several cases, SCP-1423 affected subjects would begin keeping 
journals based on their dreams. If SCP-1423 is not removed from 
the subject's possession at this time, they will neglect all activities 
that do not relate to SCP-1423. 


However, after 3-5 months of exposure, subjects will begin to 
document major alterations to their dreams. Subjects may report 
elements not found in their vacation, instead claiming that they are 
no longer able to remember their dreams "properly." They will 
continuously attempt to utilize SCP-1423's effects, with each dream 
becoming longer and less related to their original experience. This 
effect will persist indefinitely. 


SCP-1423 was recovered from the home of , who had been 
reported missing by his neighbors. After local authorities reported on 
SCP-1423's anomalous effect, Foundation personnel were able to 
intervene and suppress the reports. Class-C amnestics were 
administered to witnesses. However, had been previously 
administered amnestics in 1976, after he was present at Kirk 
Lonwood High School during Incident-SCP-332-A. Class-A 
amnestics were givento Mr. __, and investigation into this 
connection is ongoing. 


Addendum: Documents recovered from an SCP-1423-affected 
subject. 


It's endless, and never-ending, and all those other words 
for too damned long. We've got our vans and the roads 
ahead, but we never get anywhere. We're always 
"closer" to the concert. Well, it's a concert today. 
Yesterday we were headed to Miami, to go and see the 
coral castle. Last Tuesday it was Washington, to get 
together with the suffragists. Suffrage? God, that ain't 
right. We ain't right about anything. 


| really, really want to just grab Jerry in his fucking face 
and yell HEY WE'RE NEVER GETTING ANYWHERE 
ITS JUST THE SAME SHIT, YOU DUMBASS WHEN 


DO WE GET THERE but he won't hear, because | won't 
say it. I'm relaxed here and rolling through the hills of 
technicolor grasses and farms. We passed the Boyd 
farm about 11 times yesterday, and every time it had the 
same rusty gate out front. | think | saw someone resting 
on the porch once, with depraved, hollow eyes that 
followed down the road 


It wasn't swamp gas. 


You almost look forward to class now. Class? God, | 
haven't thought of going back to class in months, maybe 
years. | remember seeing that tightwad Nathan, with his 
stupid face and rusty glasses. Man, | used to want to 
punch his mug every time | saw it, with that dumb, 
oblivious grin. Shit, if | saw him now... | dunno. Maybe 
I'm over-thinking this. 


We'll be at the concert tomorrow anyways. | can't wait to 
see Amy again 


Roads go on, climbing up the cracked highway. Jamie 
tried to buy back his soul, with a dime he found under the 
cushion. Stuck it in like a penny arcade, and we watched 
him spin. The sun's ahead of us, burning and crumbling 
with some light dancing between the trees lining the 
road. They aren't trees, really. More like puppy dog tales, 
wriggling in the wind. Found the postcard from Dad 
again. Hopes my vacation will be as good as the one he 
took. 


| hope he's wrong right.

1. Subjects who never attended high school, or never had a summer 
vacation will report the last summer they experienced.

SCP-1424: Patches 


Item #: SCP-1424 
Object Class: Safe 


Special Containment Procedures: SCP-1424 is to be placed in an 
airtight, 2 x 2 x 2 m cushion-lined containment pen. The area is to be 
monitored biweekly to confirm the subject's physical condition. 
Personnel are to equip gas masks when entering the area. The 
containment cell is to be filtered for gas daily. 


Description: SCP-1424 appears to be a juvenile dog of the Alaskan 
Malamute breed. A platinum chain choke collar around its neck 
reads "Patches, for my Sweetheart". Behavior of SCP-1424 is 
typical of juvenile dogs. 


SCP-1424 has a body temperature that ranges between -23 to 
-18 °C, and continually exudes substantial amounts of ammonia 
through its tongue and paws, causing a significant health risk to 
personnel exposed in an unventilated space for a long enough 
period of time. How this compound is produced from SCP-1424 is 
not yet known. 


SCP-1424 also displays a number of other physical abnormalities: 


¢ SCP-1424 shows no vital signs. Bodily organs are intact 
although non-functioning. 


* SCP-1424 does not react to what would normally cause an 
organism physical pain. 


* SCP-1424's body does not heal from injury. 


* SCP-1424 has not been shown to respond to sound, light, or 
smell, although its motor and vocal abilities do not appear to 
be inhibited. 


* SCP-1424's eyes do not appear to be functional, as it has 
been seen colliding with walls occasionally when moving 
around its containment pen. 


« It cannot be ascertained whether or not SCP-1424 sleeps or is 
simply not moving. 


SCP-1424 moves around its containment pen in a predictable 
pattern each day, only deviating from this repeated behavior when 
interrupted. When placed into a different cell, SCP-1424 will simply 
repeat the pattern of movement that was exhibited on its first day 
present in its new surroundings. 


Special precautions are to be taken when moving and testing 
SCP-1424 for preservation purposes. 


SCP-1424 was discovered at an animal shelter in Los Angeles, 
California, following multiple failed euthanasia attempts. Witnesses 
were administered amnestics and the SCP was recovered without 
incident. Staff at the shelter report the owner being extremely 
distressed when delivering SCP-1424 to their facility, placing 
SCP-1424 on the counter and immediately leaving. No additional 
information on the previous owner was found. 


Autopsy Report 1424-A: 


Special precautions were taken during extraction of the contents of 
the stomach and intestine to prevent unnecessary physical damage 
to SCP-1424. As expected, SCP-1424 did not react with distress 
and shows no signs of inhibited movement or vocal ability after the 
procedure. Contents of stomach were identified to be a chewed but 
undigested steak, miscellaneous paper material, and one (1) 2.41 
CT diamond encrusted ring set in 14k white gold.

SCP-1425: Star Signals 


Item #: SCP-1425 
Object Class: Safe 


Special Containment Procedures: A single copy of SCP-1425 is to 
be kept in a double-locked archive in Storage Site 40. Access to the 
document is to be completely restricted barring express written 
permission of at least two of the following officials: the Site Director, 
the EID Chief, the CMA Head, or an O5 personnel. A second copy is 
contained in an undisclosed location under procedures divulged only 
to O5 Council members. All forms of printed and televised media 
available throughout the United States are to be monitored for the 
appearance of keywords and key symbols from the list provided in 
CMA Document 1425-A. Any located additional copies of 
SCP-1425 are to be turned over to CMA custody for destruction. In 
the event that a second SCP-1425 event begins to manifest, contact 
an Official listed above immediately to initiate Protocol Ophiuchus. 


Description: SCP-1425 is a hardcover book, measuring 20 cm x 

35 cm x 5 cm and published in 2005 by the company [REDACTED] 
Books (now defunct—see Operation Stargazer files). The front cover 
bears the title "Star Signals". The back cover has the following 
description: 


Did you know that some stars in the sky are dead, but 
we still see their ancient image? 


With the best-selling novel Star Signals, sold in four 
countries and translated into hundreds of languages, you 
too can tune in to the celestial frequencies, and then 
become like the stars! 


When a subject reads the full text of SCP-1425, the book exerts a 
mild reality-warping effect, influenced by the subject's desires (which 
in turn are influenced by SCP-1425; see below). When a sufficiently 


large number of subjects are exposed to this effect, further 
complications arise in terms of mental health and the integrity of 
spacetime. See Event Log SCP-1425-05.
