SCP-6058 during testing.
Item #: 6058
Object Class: Safe
Special Containment Procedures:
All entrances to SCP-6058 have been fitted with gated steel barriers to prevent public access. A security station has been erected on-site under the guise of a telecommunications station for the purpose of on site surveillance and a testing location.
Individuals possessing knowledge of SCP-6058s anomalous nature prior to containment are to be discredited and amnesticised when possible, an effort made easier by the local populations historic reluctance to share knowledge of SCP-6058.
Objects manifested by SCP-6058 may be utilised, kept and studied, with particularly notable or anomalous manifestations to be housed within Site-40.
Description:
SCP-6058 is the leftmost of three storm drainage tunnels connecting a small waterway to sea located in the town of ██████████ in southern Victoria, Australia. The tunnel is constructed of rebar reinforced concrete, measuring 1.7 metres in diameter and 15 metres in length, and frequently channels low amounts of water to the ocean.
SCP-6058 largely functions as a non-anomalous storm drain, with it's primary anomalous effect only manifesting when entered by lone persons from its south (Ocean facing) entrance. When a subject enters and traverses SC-6058 from this direction the subject which they were thinking about within the tunnel will spontaneously manifest in the glade outside the north entrance of SCP-6058.
Tunnel what makes what you're thinking about as you walk through it appear on the other end, no matter how wacky.
