SCP-4273
“Music of the Sands”
Item Class: Keter.
Special Containment Procedures:
SCP-4273-1 is currently contained underneath of SCP-4273-3, in the center of SCP-4273-2. While SCP-4273-1 has been relatively easy to contain, SCP-4273-2 is currently uncontainable by foundation personnel, due to its massive size, the resources required to do so, and the fact that SCP-4273-2 is common knowledge to the public and attempting to contain SCP-4273-2 would cause global backslash and suspicion. Foundation agents in nearby governments including but not limited to Namibia, Botswana, South Africa, and Angola, are to ensure that no testing or deployment of any kind of nuclear or radiological devices are to be tested within the limits of SCP-4273-2. Agents stationed in populated areas close to SCP-4273-1 and SCP-4273-3 are to prevent any government or corporation from excavating in a five (5) mile radius around SCP-4273-1 and -3. SCP-4273-3 is to be open to the public for site-seeing purposes only. The daily expansion of SCP-4273-2 is to be blamed on global warming.
Description:
SCP-4273-2 refers to an area within the nation of Namibia known as the Namib Desert (notes: this is not related to SCP-777 in any way so please stop asking), which is currently covers an area of approximately 31,274 squared miles. SCP-4273-1 is located underneath the rough center of SCP-4273-2, grid coordinates [REDACTED]. SCP-4273-1 is a subterranean chamber that contains various devices of unknown, possibly extraterrestrial, origins. Everything within the chamber, excluding the sand from the entrance into the chamber, is coated with an unknown metallic substance, which appears to be impervious to physical damage by foundation testing (see document SCP-4273-A). It is hypothesized by staff that the substance was used to prevent damage from numerous sources from destroying the items contained in the chamber. It appears that the entire chamber is powered by a roughly one (1) foot in diameter, two (2) foot tall dome with strange symbols and glyphs written on its surface. There is a handle-like structure on the direct top of the central dome. The dome is also coated in the same metallic substance as the rest of the structures in the chamber.
Within the chamber are approximately 458 hollow tubes that create various sound waves, both audible and inaudible to the human ear. It has been shown that, as the tubes continue to make noise, the edges of SCP-4273-2 appear to expand at a rate of roughly [REDACTED]millimeters per day. A number of these frequencies were recorded and remade in a modified testing chamber, a log of which can found in document SCP-4273-B. It has been shown that the combination of all 458 frequencies combine into an inaudible, singular frequency that can turn any material into sand, provided the material is exposed to the frequency for a certain length of time (see document SCP-4273-B). It is theorized that SCP-4273-1 may have been an attempt by unknown extraterrestrial races to terraform earth into a desert world. For what purposes this may have been done is currently unknown.
The chamber is filled with lethal levels of atomic radiation which emanate from the central dome structure. Thankfully, the radiation quickly dissipates after exiting the chamber (notes: Remember people, just because the radiation goes away when you leave the thing, it doesn’t mean you won’t get cancer, researcher [REDACTED] is still in chemo, so make sure you follow safety protocols). Carbon dating places SCP-4273-1 at just over 55 million years old, which, if true, means that the entirety of the Namib Desert was created by SCP-4273-1. Due to testing performed on [REDACTED] as a part of document SCP-4273-A, the chamber seems to absorb external radiation as energy. During the final stages of testing, a small nuclear explosive was placed inside of SCP-4273-1, and the chamber sealed shut. After the resulting radiation spike, civilians of the nearby native African villages reported that the desert seemed to move and grow rapidly. All non-foundation personnel who witnessed the event were tracked down and given class B amnestics. All nearby personnel and materials in a 2.3-mile radius were nearly instantly turned into sand. This resulted in [REDACTED] foundation casualties, and the elevation from Euclid to Keter classification.
Document SCP-4273-A: Metal test log:
On [REDACTED] multiple attempts were made to test the unknown metal covering SCP-4273-1’s interior.
Test #1: Iron hammer and chisel. Result: after multiple hammer strikes, the iron chisel broke into two (2) pieces. Failure.
Test #2: Sledgehammer. Result: the sledgehammer bounced off of every structure hit, in one instance, bouncing off the surface with such force, that junior researcher Abara was struck in the shoulder by the flying tool and had to be airlifted to the hospital for immediate surgery after the impact shattered her collar bone. Failure.
Test #3: Jack hammer. Result: after roughly 2 and a half minutes of hammering, the jack hammer began to emit dark smoke and was removed from the chamber and discontinued for the safety of personnel. Failure.
Test #4: Diamond drill-bit. Result: while the drill-bit itself did not break, neither did the metal. Failure.
Test #5: Thermite explosive charge. Result: the spot where the device went off was covered in soot, however when cleared away showed no actual damage to the structure. Failure.
Test #6: Mini nuclear explosive device/ “Briefcase bomb”. Result: The radiation from the explosion was absorbed by SCP-4273-1 which resulted in the deaths of [REDACTED] personnel and civilians, as well as the Namib Desert expanding by roughly 17 feet in all directions, however the internal structure of SCP-4273-1 looked as though nothing had occurred. Failure.
Document SCP-4273-B: Frequency test log:
Test #1:
Subject: one (1) medium meat-lovers pizza.
Result: At one (1) hour and thirteen (13) minutes, the crust and tomato sauce began to turn into sand, the cheese began to sandify at one (2) hours and thirty-nine (23) minutes, and the meats began at two (2) hours and fifty-eight (58) minutes. After a period of roughly two (2) hours and forty-seven (47) minutes from initial sanding, the crust and tomato sauce were fully sandified, the cheese after five (5) hours and thirty-six (36) minutes, and the meats fully turned into sand after seven (7) hours and seventeen (17) minutes.
Notes: Senior janitor Russell was commended for his willingness to sacrifice to the foundation, by giving up his dinner so the tests could begin before the official test subjects arrived, he was accordingly bought an extra pizza by research staff and allowed to tale the rest of the day off.
Test #2:
Subject: one (1) copy of the novel, Moby Dick.
Result: At two (2) hours and forty-one (41) minutes of exposure, the cover and pages began to turn to sand, and was fully sanded after an additional two (2) hours and twenty-five (25) minutes.
Notes: none.
Test #3:
Subject: one (1) standard Namibian infantry mess kit /w M.R.E.s included.
Result: At one (1) hour and eleven (11) minutes of exposure, the M.R.E. began to turn into sand. After a further one (1) hour and twenty-one (21) minutes, the M.R.E. had completely dissolved into sand. At four (4) hours and thirty-four (34) minutes the plastics in the mess kit began to chip on flaks of sand, and after six (6) hours and forty-five (45) minutes the mess kit was swept up and thrown out into the desert.
Notes: It appears as though the frequency has a harder time transforming strong, man-made materials, while more naturally occurring materials, such as organically-based substances and foods, decay at a much faster rate.
Test #4:
Subject: one (1) twenty (20) lbs. ball of titanium.
Result: At roughly thirteen (13) hours and thirty-six (36) minutes from initial exposure the ball began to degrade, and around eight (8) days two (2) hours and fifty-one (51) minutes, the ball had finally been completely reduced into sand.
Notes: It appears as though the previous hypothesis put forward by Assistant Researcher Jalal on the rate of decay is correct.
Test #5:
Subject: D-11564
Result: [REDACTED]
Notes: We are currently scheduling counseling for the two (2) janitorial staff who had witnessed the expiration of, and then had to sweep the aftermath, of D-11564.
