Item #: SCP-F-212
Object Class: Euclid
Special Containment Procedures: SCP-F-212 is to be closed to the public under the pretense of protecting its delicate gypsum formations. Suppression of information has been deemed unnecessary as the vast majority of the general public already considers it an urban legend. Foundation agent John Graham is tasked with maintaining a websitehttps://grahamjw.wordpress.com/2009/09/17/ted-the-caver-mystery debunking SCP-F-212 as such.
Description: SCP-F-212 is a 323.7 m section of the Timpanogos Cave System in Utah, publicly known as Interstate Cave and Freeway Cave. Its geology is consistent with that of other caves in the system.
SCP-F-212-1 is a section of the cave located approximately 30 m from the entrance. Contained within SCP-F-212-1 are an unusually round rock and hieroglyphics; the meaning of the latter is currently unclear. All photography within SCP-F-212-1 inexplicably fails; analog photographs appear as overexposed while digital images and videos show only static.
Subjects that approach SCP-F-212-1 generally report feelings of unease, fear and paranoia. The effect intensifies as they go deeper into the cave; D-class personnel tasked with exploring SCP-F-212 have reported hallucinations even after leaving. Subjects that spend a prolonged time in SCP-F-212 often show signs of extreme distress but will invariably refuse to elaborate. Animals appear to be more sensitive to the effects and will exhibit fear long before humans detect anything out of the ordinary.
SCP-F-212-2 is the placeholder designation for the entity residing within the cave. Although no such entity has yet been directly observed, D-class personnel have encountered anomalous phenomena that infer its existence:
* Low rumbling sounds, determined to be unrelated to passing vehicles on Utah State Route 92.
* Occasional loud screams, described as "unworldly" and "inhuman" by researchers. Acoustic imaging suggests that the sounds originate from a hole in the cave; the hole is currently too small for ingress.
* Sporadic air currents from the same inaccessible section of the cave. Attempts to locate the exact source of the airflow have also been unsuccessful.
Addendum F-212-1: SCP-F-212 came to the Foundation's attention following the disappearance of two speleologists, one of whom kept an online journalhttp://www.angelfire.com/trek/caver detailing their findings. Efforts to discover the whereabouts or remains of either subject have thus far failed. The journal is allowed to remain online as it is generally believed to be fiction.
