Description: SCP-1638 designates a roughly circular forested area 
approximately five kilometers in diameter located in [REDACTED] 
County, California which is centered on the grave of Z_ Smith,a 
Foundation Containment Specialist specializing in acoustic SCP 
objects, who died on / /20 due to liver cancer. Testing of the 
gravesite as well as of the exhumed remains revealed no 
anomalous effects. Flora in area consists mostly of Monterey pines 
(Pinus radiate) and Blue Gum (Eucalyptus globulus) trees. The area 
also maintains a population of Monarch butterflies (Danaus 
plexippus) which occur in numbers _ percent higher than in similar 
environments; hereinafter referred to as SCP-1638-1. SCP-1638-1 
do not display normal migratory behavior and remain within the area 
year-round, but display no individual anomalous behavior outside of 
a Harpo event. 


Individually, none of the flora, fauna, or inorganic features of the 
area displays any anomalous behavior or biology. However, taken 
collectively, the combined surface geometry of all these elements 
within SCP-1638 display a powerful anechoic effect - such that the 


ambient sound level within the area is generally no higher than five 
decibels. Observation and testing have revealed that SCP-1638 is 
capable of dynamically controlling most natural surface geometries 
(including leaves, forest ground detritus, and invertebrate fauna) 
such that sound energy is either absorbed, or destructively canceled 
by either another source or its own echoes. Of note, in several 
instances, SCP-1638 makes use of several noise cancellation 
techniques that have been developed exclusively for Foundation use 
in the containment of acoustic-based SCP objects. 


Any sound exceeding 85 decibels at its source which is sustained 
for longer than 10 seconds within SCP-1638 will trigger a Harpo 
event. During such an event, SCP-1638-1 within a kilometer radius 
of the source of the sound will display swarming behavior and 
congregate in an area around the disturbance. Once a critical mass 
of SCP-1638-1 is reached (at least 50,000), instances of 
SCP-1638-1 will collectively position their wings such that an 
amplified version of SCP-1638’s normal anomalous effect occurs. 
Testing shows that sound levels during such an event approach as 
low as -14 decibels, even when sound is generated by PA speakers. 
D-class personnel exposed to the event reported that they could 
hear only themselves, as well as mild to moderate psychological 
distress consistent with partial sensory deprivation. A Harpo event 
generally lasts approximately three hours after the disturbance. 


Attempts at establishing communication with SCP-1638, or 
ascertaining whether it has sentience, have thus far met with failure. 


Addendum SCP-1638-A: SCP-1638 came to the attention of the 
Foundation when construction crews attempting to clear the area for 
development triggered a Harpo event. Standard procedure was 
followed and the construction crews were interviewed, and then 
administered class-A amnestics. Specialist Smith's gravesite was 
discovered during a search of the area, as were several other items 
(See Addendum SCP-1638-C) 


Addendum SCP-1638-B: 
Internal Investigation Report / /20 : 


Foundation records show that Specialist Smith grew up in the town 
of _, California located ten kilometers away from SCP-1638, and 


investigation reveals that she had made several unsuccessful 
petitions whose goal was to block development of the area that 
currently contains SCP-1638. Specialist Smith was originally 
cremated and buried at the cemetery in __, aS per standard 
Foundation protocol for personnel with no immediate surviving 
family. However, her remains were illicitly exhumed and reburied at 
their current location by an unknown person or persons at a later 
date; this was not discovered until SCP-1638 came to Foundation 
attention despite security measures at the cemetery. Specialist 
Smith's original gravesite currently displays no anomalous effects, 
but is to be monitored for emergent effects. 


Addendum SCP-1638-C: 


Text of a letter found on top of Specialist Smith's gravesite, 
addressed to the SCP Foundation, and signed"C M "—a 
person of interest whose involvement is suspected in a large 
number of acoustic SCP objects, of which Specialist Smith was at 
least partly responsible for containing. 


| hated her at first. She contained my art, neutered it, 
killed it | thought. So | honed my craft, created something 
new and set it free - but you caught it and she caged it. 
Rinse. Repeat. And again. Somewhere along the line 
though, hate became rivalry became... honest 
competition. She pushed me, and | pushed her. How 
many monsters would be free, how many lives lost, if she 
hadn't learned from me? If not for her, I'd probably still be 
rubbing horsehair on wire. 


Once, | stayed, hidden, to watch her contain one of my 
pieces — | was still competing with her then, and | 
thought it would give me an edge. It was foolishness, | 
only understood the barest portion of her art. Instead, | 
realized that we'd created something new. Somewhere 
between my sound and her silence a new art was being 
born, a beautiful fractal edge of clarity. | think | fell a little 
in love with her then. 


We created many pieces together that way, though I've 
never been able to convince myself completely that she 


felt as | did about them. And now she's dead. And all 
you've given her for her years of service is an 
anonymous grave, and perhaps her name carved ona 
rock somewhere among countless other such names. 


She was a worthy adversary, a great rival, and an 
unmatched partner. She deserves more. Contain — or 
rather, preserve — this place that she loved, you owe 
her that much. As for myself - I'm not capable of building 
her a suitable monument - so I've seen to it that she's 
gotten a chance to build her own. 


Regards, 
Cc OM

SCP-1639: The Jazz Station 


Item #: SCP-1639 
Object Class: Safe 


Special Containment Procedures: SCP-1639 is to be kept in a 
secure room, of any reasonable size. All audio from SCP-1639 is to 
be recorded and submitted for analysis weekly. Should any 
researcher request SCP-1639 for testing, the request must be 
approved by Site Director 


Description: SCP-1639 is a brand portable radio, measuring 
230 x 120 x 70 mm. The item's casing is red plastic, and shows no 
signs of wear. SCP-1639 still bears its product ID, and as such has 
been traced by Foundation operatives to the factory in Surrey, 
UK. This model was produced between the years 1979-1982. A 
piece of red tape marks the longwave frequency 2 . kHz onthe 
frequency tuner. 


SCP-1639 exhibits no unusual properties when set to receive FM 
radio stations. However, when long wave radio is selected, 
SCP-1639 will receive a signal at 2 . kHz, despite this frequency 
being reserved for aeronautical navigation aids. No radio station is 
known to have ever broadcast at this frequency, and other radio 
systems receive no transmission even when placed directly beside 
SCP-1639. The signal received is henceforth designated 
SCP-1639-1. 


The content of SCP-1639-1 is mainly in the form of jazz music (93% 
of studied audio). The majority of the songs heard are pieces known 
to exist, though a fraction (approximately 4% of studied pieces) have 
been so far heard exclusively though SCP-1639. These pieces are 
markedly different, utilising fewer instruments and with lower sound 
quality. The remainder of the signal content is an individual 
(henceforth designated SCP-1639-2) speaking. SCP-1639-2 will 
usually appraise the pieces that have recently played on 


SCP- 


1639-1, though occasionally SCP-1639-2 will begin to discuss 


various topics, including: 


SCP- 


Jazz 

Poems written by SCP-1639-2 
Stories written by SCP-1639-2 
Firearms

SCP-1640: Lunar Leporine 


Item #: SCP-1640 
Object Class: Neutralized; Previously Safe. 


Previous Special Containment Procedures 1/23/2011: 
Observation Probe Delta-6 is currently in orbit, in order to intercept 
any radio signals emitted by SCP-1640. SCP-1640's trajectory has 
been altered to prevent escape velocity from the Moon, and is 
estimated to impact the Moon on 4/14/2035. Knowledge 
suppression of SCP-1640 is currently in process with select 
individuals of NASA. Observation of SCP-1640 is currently being 
held at Research Sector-29, and any changes in orbit or velocity are 
to be reported immediately. 


Exploration Probe Delta-7 is tasked with collecting and disposing of 
instances of SCP-1640-1, and must be replaced before ceasing 
function on 8/24/2059. 


Revised Procedures: As of 4/10/2011, Exploration Probe Delta-7 is 
now tasked with removing destroyed instances of SCP-1640-1 and 
debris from SCP-1640. No further containment procedures are 
necessary, see Neutralization Event 1640-A. 


Description: SCP-1640 is a hemispheric mass of condensed soil, 
with several artificial pieces of equipment affixed to its surface. It is 
estimated to be 10 meters in diameter and 6 meters in height. 
SCP-1640 is approximately 5,000 kilometers above lunar surface, 
and is equipped with sub-systems typical for a modern man-made 
satellite. However, they are affixed in various positions as to imitate 
a temperate forest. This includes: 


¢ Green, circular solar cells attached to large, brown metal rods. 
Back-up batteries are held inside each rod, assumed to be an 
alternate power source. 

¢ Dual magnetometer sensors, UHF antenna, and telemetry 


control antenna, each positioned on the edges of SCP-1640. 
Each is mounted by a flower blossom, supposedly artificial. 

« The main thrusters are positioned underneath the main mass, 
and are bent at angles not unlike roots. 

¢ Irregularly shaped supplementary telemetry equipment, similar 
in appearance to stones. Apparently used in creating radio 
signals. 


SCP-1640 emits a frequency modulated radio broadcast on the 
frequency band, and may occasionally broadcast sounds of a 
repeated thumping noise, which has been determined to be Morse 
code. 


SCP-1640 consistently produces various species of flora, and 
releases said specimens through an exhaust port located at its rear. 
Recorded specimens include shrubbery, saplings of trees, and 
various vegetables (edible buds, roots, leaves from various plants). 
These specimens (hereby referred to as SCP-1640-1) display no 
adverse effects when exposed to vacuum and ultraviolet-rays. They 
will continue to grow normally, and though processes such as 
photosynthesis are continually conducted, the lack of necessary 
materials (water, COs, etc.) will not impact their lifespan. Instances 
of SCP-1640-1 were observed to disintegrate from atmospheric 
descent, and show no resistance to any other form of damage. 


Images of SCP-1640 have confirmed the presence of a rabbit 
(Lepus curpaeums) above SCP-1640, though its size suggests that 
it is either newly born or the runt of the litter. It is currently unknown 
how this specimen is able to remain situated on SCP-1640 or how it 
is able to survive without any form of protective covering or shelter. 
Contact with SCP-1640 is currently being devised to detect any 
other anomalous properties of SCP-1640's inner mechanisms and 
its inhabitant. 


Addendum 1640-C: The following are radio transmissions received 
from SCP-1640, at the time of discovery. The last transmission was 
received during SCP-1640's neutralization. 


3/ /20 
| see home below me. You must be lonely, | bring you 
back presents. 


3/1 /20 
The moon rabbit, huge. He is fields wide! 
Also breach in ship. Gifts falling out. Will try fix. 


3/2 /20 
Above the moon! All the white rabbits below, they're 
sleeping. Landing soon! 


3/3 /20 
Still above moon. When is landing? 


4/ /20 
How will deliver gifts? When is landing? Home? 


The following transmission was found to originate from 
[REDACTED], which was notably home to a warren of rabbits, and 
was designated as Anomalous Event 3450-UT. The time between 
the transmission from SCP-1640 and the Anomalous Event has 
suggested that it was communicating with SCP-1640. [REDACTED] 
has displayed no anomalous properties as-of-yet. 


Child. A satellite goes in one direction. | sent you alone, 
because you need strength. Because your life needs 
purpose, since it has none. So this will be your task from 
now on: to deliver to the rabbit in the moon for me. You 
are doing wonderfully. 


Neutralization Event 1640-A: On 4/ /20 , control noticed a 
deviation in SCP-1640's flight path. It aopeared to have manually 
diverted from its standard orbit, and had begun to fall towards the 
lunar surface. Personnel were unable to prevent SCP-1640's crash- 
landing and destruction. Upon observation of the crash site, all plant 
life had lost their anomalous properties, and began to display effects 
typical of exposure to vacuum and high temperature. No further 
radio signals were transferred from SCP-1640, leading to its 
classification of Neutralized.
