By Order of the Overseer Council

Certain parts of this file are subject to Level 4 or higher classification.

Research into SCP-1730 is currently ongoing. Individuals involved in research may be subject to the effects of known or unknown cognitohazards. Information on these hazards is on a need-to-know basis only.

Individuals attempting to subvert these classification measures will be subject to immediate termination by a Class VIII "Red-Kill" anomalous memetic hazard.


Main office of SCP-1730. Primary access to basement levels is below this structure.

Item #: SCP-1730

Object Class: Euclid

Special Containment Procedures: A circular perimeter has been established 2km from SCP-1730, and a quarantine zone has been established 1km from SCP-1730. Personnel who are to enter SCP-1730 must first undergo Class VII Hazardous Contact preparation measures, including the application of a modified "Maxwell-Harden" hazardous material reinforced airtight suit. The application of these protective measures may only take place at the Provisional Site-23 quarantine main gate.

Individuals attempting to exit the quarantined area must first submit to thorough decontamination protocols as administered by the quarantine security staff. Individuals failing to meet the quarantine extraction parameters are to be held for further decontamination or, in the event decontamination becomes unfeasible, termination.

Containment Update ██/██/████: Dangerous biological and cognitohazardous entities have resulted in high casualties of security rescue teams. Mobile Task Force Zeta-9 "Mole Rats" has been assigned to all current exploration efforts.

Containment Update ██/██/████: Due to the events detailed in Exploration Log 7, all future exploration of SCP-1730 has been suspended indefinitely, pending Overseer approval.

Containment Update 02/01/2016: Due to information gathered by Foundation surveillance teams, exploration and recovery efforts into Site-13 are no longer indefinitely suspended. Details will be available on a need-to-know basis. Assigned Mobile Task Force units will be alerted by their superior officers.

Description: SCP-1730 is a large complex of structures 15km northwest of the US/Mexico border within Big Bend Ranch State Park that was discovered on June 5th, ████. Due to the isolated nature of the complex, and the low survival rate of individuals who come in contact with it, it is possible that SCP-1730 had been previously discovered but unreported.

SCP-1730 bears identifying markings and contain documents to support the claim that SCP-1730 was at one point Foundation Site-13, originally located near Nome, Alaska. This conflicts with current records, which show that Site-13 was a project that, while intended to be constructed in Nome, was scrapped for the larger and more advanced Site-19 and never completed. Flora located on-site have been traced back to those native to the Alaskan region. How SCP-1730 came to be at its current location is unknown.


The SCP-1730 power station.

SCP-1730 is in a severe state of disrepair, and appears to have been left abandoned for an extended period of time. The site power generator has continued to operate in a damaged state, despite a number of fuel leaks and fires throughout the facility. This has resulted in intermittent power failures throughout the site, hindering exploration and rescue efforts.

The origin of SCP-1730 is unknown, as is the nature of many of the anomalous entities contained within. It is confirmed that the 2nd through 15th1 basement levels were utilized for entity containment, though the state of that containment has deteriorated significantly.


Message located on SW stairwell leading to third basement level.

It is believed that a contingent of human survivors exists somewhere deep in the lower basement levels of the facility. Messages written in English have been discovered throughout the site, consisting of warnings such as "danger" and "death here", and other messages such as "not my body" and "bleed". A recurring message, "What happened to Site-13?", has been found in several different locations in the basements.

Several logs of data have been collected by the remaining functional site terminals, the relevant data of which is contained in the addendums below. Worth noting is that inconsistencies exist between the logs and what has been determined through exploration, including site layout, staff makeup, and contained anomalies.

Addendum 1730.6: Received Audio Transmission

The following audio transmission was picked up on monitoring equipment on the morning of February 1st, 2016. The transmission, both speech and an encrypted signal that followed, has been repeating on a continuous loop since it was first detected. The contents of the transmission are accessible below.

Addendum 1730.7: Updated Exploration Memorandum

In light of recent information gathered by Foundation surveillance teams, it has been deemed pertinent to once again send exploration and recovery teams into Site-13. By order of Overwatch Command, SCP-1730's containment procedures have been updated. Details to follow.
