 Item number SCP-1044 Object Class Safe Special Containment Procedures SCP-1044 is to be surrounded at all possible access points by signs in English and French, warning of falling rocks, avalanches, landmines, and dangerous animals. The area should be kept under periodic aerial surveillance, and at least one member of personnel will be available in short notice to further discourage any non-personnel who choose to ignore the warnings. Description SCP-1044 is located in a small, uninhabited valley in the Alpine region of France, located at ██████ Degrees north ████ Degrees east, and measuring approximately 1.2 kilometers across and 0.6 kilometers wide at its broadest point. The properties of SCP-1044 were first encountered in 1968, after rumors of unusual sounding echoes began to spread through the local area. These reports range from the valley producing echoes that talked back to ████, while the reported phenomena were widely dismissed as urban legend by local authorities. Researchers were dispatched on March 6, 2000 ████ to determine their veracity. The following are partial transcripts of the three investigations carried out over the course of the following two years. Experiment 1044-1 How should we begin? Perhaps hello? Hello? I didn't get that. Try harder. Hello? Goodbye? Did you hear that? That was good. I got it. Let me try something else. Is anybody down there? Is anybody up here? Yes. No. Hold on. Try that again. As loud as possible. Yes. No. Yes. If the first echo is contradicting you, is the second echo contradicting the first echo? Or the second echo was just my own echo coming through late. Let's continue. Experiment 1044-2 Note, henceforth it can be assumed that the responses of SCP-1044 are heard in the form of an echo, in the same voice as the person who made the initial statement. Dog! Dog! I suppose there is no opposite statement to Dog. Cat? Not a true opposite. The phenomenon appears to follow a consistent logic. Observe. I am a man! I am not a man! And so, rather than echoing, I am a woman, it attempts to relay the logical opposite. It is not yet clear that it has the awareness required to attempt anything. What about the hello from the previous experiment? The echo said goodbye. It would make sense, possibly, that a statement of parting ways is logically opposite to a statement of greeting. Maybe. Or it is not as logically infallible as we think. Suggesting what precisely? Experiment 1044-3 Analysis of the audio transcripts of the experiments all conclude that SCP-1044 is an echo. It is localized to a single valley that directly contradicts the speaker wherever logical contradiction of a statement or question is possible. Where multiple echos are heard, each subsequent echo will contradict the previous. In the later experiment, attempts were made to test SCP-1044 by calling out self-contradictory statements such as, this sentence is false, this invariably resulted in, future experiments are to avoid such attempts.
