The following is the file for SCP-XXXX as it was initially created. It has since been upgraded to Level 4 SECRET and KETER, and its file is pending revision. See addenda for details.

Secondary Class:
Disruption Class:
Risk Class:



Special Containment Procedures: The land immediately surrounding SCP-XXXX has been obtained by the Foundation and is subject to standard anomalous location security measures. Any anachronistic biological samples obtained from within SCP-XXXX are to be cataloged and forwarded to containment at Site-7. Further containment procedures are pending investigation.

Description: SCP-XXXX is a water-filled sinkhole, approximately 300 meters in depth, located within the Huron-Manistee National Forest in Michigan. Geological analysis indicates that SCP-XXXX includes a tunnel complex accessible from passages located at and near its bottom.

Periodically, organisms are found within SCP-XXXX. While none have ever displayed actual biologically anomalous attributes, virtually none of these organisms (excluding surface algae and bacteria, and any vegetation or animals in the immediate vicinity) are of known species. Many display physiological and genetic abnormalities that make them difficult to classify using ordinary scientific taxonomy.

SCP-XXXX's unusual properties were initially documented by Matthew Donnelly, a park ranger and amateur biologist employed in the park. Donnelly published photographs, anatomical studies, and other documentation regarding life found within SCP-XXXX on a personal blog between 2017 and 2019. His data were regarded as an obscure hoax in the scientific community until January of 2019, when Professor J. Kirk, a former teacher of Donnelly's, visited him and found his evidence to be valid. Kirk passed on some of this information to his university's press, whereupon embedded Foundation agents intervened.

Since then, a team of Foundation operatives consisting of Dr. Laura Maksly, Junior Researcher Danica Showitz, and four security personnel have been studying SCP-XXXX.

Addendum XXXX-1: Initial Exploration Attempts

After repeated requests from SCP-XXXX's supervisory personnel, additional scientific personnel were dispatched to directly survey its interior on January 22nd, 2020. A team of four descended into SCP-XXXX in a MARDUK-type exploration submersible. After descending most of SCP-XXXX's depth (221m), the team's pace of radio contact began to dramatically accelerate. Live communication could not be maintained, and, over the next several minutes, their transmissions became increasingly garbled and dense before ceasing entirely.

Following the apparent disappearance of the exploratory team, two separate rescue attempts were made over the course of the next week. Each of these teams utilized the same type of exploration craft as the initial team, with the same crew composition. Contact was lost with both of these teams in the exact same manner as with the initial team. Unmanned submersible robots also experienced these results. No equipment or personnel deployed into SCP-XXXX were recovered.

By January 31st, the pace at which unknown organisms emerged from within SCP-XXXX had accelerated to roughly seven times the maximum pace that Donnelly's research had suggested, and markedly increased following the deployment of any assets into SCP-XXXX.

Attempts to dig into the sinkhole or its tunnels from other directions were not successful, with excavators simply encountering more earth, rock, and water where logic would dictate SCP-XXXX would be. SCP-XXXX was then reclassified as a spacetime anomaly affecting the land in its immediate vicinity, and designated a higher research priority. Direct exploration (manned or unmanned) was deemed unsound until a means of safely navigating the spacetime barrier could be developed.

Addendum XXXX-2: Incident XXXX-α

On February 4th, 2020, a hostile organism resembling a cross between an Architeuthis dux,1 a Nautilus belauensis,2 and an unknown crustacean similar to those of the Eumalacostraca family emerged from SCP-XXXX. Measuring over two meters in length and 400 kilograms in mass, this organism initially appeared benign but, when approached, strangled two of the SCP-XXXX security staff. Its termination and autopsy revealed a hollow in its midsection sealed over with a cartilegenous shell. Inside this shell was a small, crudely assembled digital radio transmitter, which appeared to deliberately short-circuit itself upon attempted disassembly.

Following this incident, SCP-XXXX was upgraded to Euclid and assigned larger research and security details. In the following days, rates of emergence accelerated to roughly twelve times what Donnelly had documented.
