SCP-XXXX "Spelunky"

Let's hope it all doesn't fall

Item #: SCP-XXXX

Object Class: Keter

Special Containment Procedures: SCP-XXXX's location is to be guarded at all times in order to prevent any civil or governmental excavation, amateur exploration, military exercise, or otherwise unauthorized scanning operation. SCP-XXXX-B instances must be guarded at all times by MTF-randomgreekletterandrandomnumber "Miner's Hat".

Sinkholes and ravines caused by SCP-XXXX-A's expansion are to be filled with {INSUFFICIENT CREDENTIALS}. Should SCP-XXXX-A still cause the collapse of the area, personnel are to report to any MTF-randomgreekletterandrandomnumber agent, with the area being closed off and treated as another SCP-XXXX-B instance.

Description: SCP-XXXX-A is a self expanding cave system mostly located beneath Chobe National Park, Botswana, that, at the time of writing, measures 5.6 kilometers and has an expansion rate of approximately 3.2 meters per year. There is currently no known way of stopping or slowing down SCP-XXXX-A's expansion.

SCP-XXXX-B is the designation given to all points in which SCP-XXXX-A encounters open sky, with what is presumed to be the original "entrance" to SCP-XXXX-A being located near [DATA EXPUNGED]. SCP-XXXX-A instances differ from other sinkholes and ravines caused by SCP-XXXX-A's expansion by eroding any material that is used to cover or fill them in the course of one to three days. SCP-XXXX-B instances can be used to access SCP-XXXX-A itself normally, though doing so is not recommended, as most SCP-XXXX-B instances tend to be far more difficult to descend and ascend than SCP-XXXX-B-1.

Addendum XXXX-B-1: The following is a description of SCP-XXXX-B-1 and the first 100 meters of SCP-XXXX-A. The exploration was conducted by MTF Delta-17 "Miner's Hat" .

SCP-XXXX-B-1 is a 5 square meter sinkhole measuring 200 meters in depth. The bottom of SCP-XXXX-B-1 is composed mostly of gravel. SCP-XXXX-B-1 differs from other SCP-XXXX-B instances by leading to a non-expanding dead end of SCP-XXXX-A, and, along side the fact that no SCP-XXXX-C have been observed leaving SCP-XXXX-A through SCP-XXXX-B-1, is presumed to be SCP-XXXX-A's origin point. As such, SCP-XXXX-B-1 is to be used as the main observation point and the main entrance to SCP-XXXX-A itself.
