Item #: SCP-2935
Object Class: Keter
Special Containment Procedures: The entrance to SCP-2935 has been sealed with a reinforced concrete plug and surrounded by a perimeter fence under the guise of an EPA environmental hazard site. No personnel are to enter SCP-2935 for any reason. All prior expeditions are classified Level 5.
Description: SCP-2935 is a limestone cave system located in rural Indiana, approximately 14 kilometers from the nearest town. The anomalous property of SCP-2935 is simple: every living organism inside the cave is dead.
This is not a chemical phenomenon. Air samples are normal. Radiation levels are normal. There is no toxin, no pathogen, no environmental factor that accounts for the deaths. Animals that enter the cave die. Plants placed inside die. Bacteria cultures sealed in sterile containers die.
The dead do not decay.
Insects, rodents, and larger animals found inside the cave system during initial surveys were preserved in perfect condition — no decomposition, no desiccation, no signs of predation or struggle. They simply stopped.
A crawlway at the deepest accessible point of SCP-2935 leads to a secondary chamber that should not exist. The cave system does not extend this far by any geological survey. The chamber contains what appears to be an irregular aperture in the rock face — a passage to a secondary dimensional space designated SCP-2935-A.
Expedition Log — Team Able, Day 1:
SCP-2935-A is identical to baseline Earth. Same geography. Same architecture. Every structure the team entered was intact, undamaged, and empty. Food on tables in homes had not decayed. Clocks had stopped. Animals lay dead in streets, in fields, in their enclosures.
Every living thing on the SCP-2935-A version of Earth died on April 20th, 20██. Simultaneously. Without apparent cause.
This is the same date the crawlway in SCP-2935 was first discovered.
Addendum — Researcher's Note:
We don't know which came first. Whether the cave killed the other Earth, or whether something in SCP-2935-A reached through and touched ours.
What we know is this: on the baseline Earth, nothing inside the cave has died since the initial survey. The effect appears to be dormant. Contained, in a sense.
What we do not know is why. Whether there is a mechanism. Whether the mechanism has a trigger.
Whether we found the cave, or the cave found us.
One member of Team Able, upon returning, submitted a report that has been classified in its entirety. The final line of the report, which was not redacted before classification, reads:
It wasn't empty. Something over there is still moving. And it saw us go.
