Item #: SCP-087
Object Class: Euclid
Special Containment Procedures: SCP-087 is located on the campus of [REDACTED]. The doorway leading to SCP-087 is constructed of reinforced steel with an electro-release lock mechanism. It has been disguised to resemble a janitorial closet consistent with the design of the building. The lock mechanism on the doorknob will not release unless ██ volts are applied in conjunction with counter-clockwise rotation of the key. The inside of the door is lined with 6 centimeters of industrial foam padding.
Due to the results of the final exploration (see Document 087-IV), no personnel are permitted access to SCP-087.
Description: SCP-087 is an unlit platform staircase. Stairs descend on a 38-degree angle for 13 steps before reaching a semicircular platform approximately 3 meters in diameter. The descent direction rotates 180 degrees at each platform. The design of SCP-087 limits subjects to a visual range of approximately 1.5 flights.
A light source is required for exploration, as there are no lighting fixtures or windows present. Light sources brighter than 75 watts have proven ineffective, as SCP-087 appears to absorb excess illumination.
Audio recordings obtained during exploration consistently capture distant vocalizations originating from an unknown source. The source is estimated to be located approximately 200 meters below the initial platform; however, attempts to approach it have been unsuccessful. Despite extensive descent, explorers report no measurable reduction in distance to the source.
The depth reached during Exploration IV, the longest recorded exploration, exceeds the known dimensions of both the building and surrounding geological formations. At this time, it remains unknown whether SCP-087 has an endpoint.
