Entrance to SCP-XXXX, prior to the current containment protocols
Item #: SCP-XXXX
Object Class: Euclid
Special Containment Procedures: The entrance to SCP-XXXX has been sealed indefinitely. Civilians who approach or attempt to enter SCP-XXXX are to be detained and amnesticized. Should an individual somehow enter SCP-XXXX, personnel or otherwise, they are to be considered lost.
Description: SCP-XXXX is a narrow cave system located approximately 12km from the town of Faun, Nebraska, with two primary anomalous properties. SCP-XXXX's first anomalous property involves the durability of its structures. Geological formations within SCP-XXXX are more durable than non-anomalous rock and highly difficult if not impossible to damage. This includes through the usage of brute force, complex mining equipment, and high grade explosives.
SCP-XXXX's secondary anomalous property occurs when any form of biological life enters a section of SCP-XXXX. Immediately upon entry, affected individuals will rendered unable to die. This effect continues perpetually for as long as an individual remains inside of SCP-XXXX, and includes invulnerability from disease, aging, physical harm, and other similar ailments.
Addendum: Prior to the discovery of its anomalous properties, SCP-XXXX was a popular location for cavers and similar hobbyists to explore. The area was particularly famous for its tight corridors and deep, narrow passageways which caused many to regard it as a 'fun' challenge for experienced cavers to attempt.
On 11/13/2011, 32 year old amateur spelunker Maurice Phillips descended into SCP-XXXX with the goal of navigating a previously uncharted section of the cave known as "Clark's ditch". After a wrong turn, Phillips instead became lodged in a dead-end tunnel, and began to cry out for help upon the realization that he was trapped. Rescue teams arrived 10 minutes later, and first attempted to free Phillips by removing him from the tunnel via a pulley device attached to his legs, although this proved ineffective.
Rescuers then tried to collapse sections of the tunnel in an attempt to widen Phillips area of entrapment, whereupon SCP-XXXX's anomalous properties were first noticed. These efforts continued for roughly a week before being deemed too dangerous to continue. The cave was soon closed to public access, with the area in which the incident occurred being sealed shut and made into a makeshift grave for Phillips, who was presumed to have expired as a result of dehydration.
Containment of SCP-XXXX was established 6 years later on 12/19/2017.
