 SCP-509 is the collective term for two structures with similar and possibly linked anomalies. SCP-509-A is a wooden sauna located in Gaston, Oregon. When activated remotely, it functions as normal for an electric stove sauna. When used by a human, SCP-509-A produces clouds of smoke instead of steam. After a period of 155 minutes, SCP-509-A returns to its inactive state, now filled with extremely thick smoke. All humans in SCP-509-A at activation are no longer present within the structure, but are replaced by an equal number of cured pig carcasses. These carcasses exhibit no anomalous properties.
