Acorrding to Tor.com, Mystery Flesh Pit National Park began as a much-loved exercise on r/Worldbuilding. The brainchild of Redditor u/StrangeVehicles, aka designer, illustrator, and writer Trevor Roberts, it has since evolved into a series of imaginary NPS effluvia showcasing the monstrous attraction.
As the name suggests, it’s a giant flesh tunnel opening through the Earth’s epidermis, dermis, hypodermis, and more, revealing colossal esophagi and leviathan spleen. As you descend, you may encounter “spasm fits” and “gastric ejecta” or feel your bodily moisture being “leeched.” Deviate from the marked trails and you risk digestion, lethal entanglement with “Macrobacteria” and “Abyssal Copepods,” or a splattering of “amniotic secretions.”
Roberts describes the MFPNP as such:
The Mystery Flesh Pit is the name given to a bizarre natural geobiological feature discovered in the permian basin region of west texas in the early 1970s. The pit is characterized as an enormous subterranean organism of indeterminate size and origin embedded deep within the earth, displaying a vast array of highly unusual and often disturbing phenomena within its vast internal anatomy.
Following its initial discovery and subsequent survey exploration missions, the surface orifice of the Mystery Flesh Pit was enlarged and internal sections were slowly reinforced and developed by the Anodyne Deep Earth Mining corporation who opened the Pit as a tourist attraction in 1976. In the early 1980s, the site was absorbed into the National Park System which operated and maintained the Mystery Flesh Pit until its sudden closure in 2007.
On Reddit, Roberts said that he's developing supplementary material (maps, guide pamphlets, etc.) for a fictional national park/national monument chiefly characterized by the existence of an enormous living organism which extends deep into earth. The origin of the pit is unknown, as well as it's ultimate size and complete characteristics. The company which discovered the pit, Anodyne Inc., has been granted a contract from the NPS to operate a tourist experience there with close oversight from the U.S. Government. Though most authorities and experts have determined that the pit is reasonably safe, new and unusual phenomena in and around it continue to be recorded.
From the National Park Service website:
"While the rural areas of west Texas are known for their sparse populations, one tourist attraction seems to continually generate a steady stream of visitors around vacation seasons. The titular "Mystery Flesh Pit" has been a wellspring of fascination for geologists, biologists, sociologists, engineers and the general public alike. Guests are advised to book age-appropriate tours and activities well in advance of their visit, as only small groups are permitted into the orifice at any given time. That said, pheromonal discharges and the overall aggression level of the MFP can vary with short notice, so visitors should be advised to be prepared for changes in schedule & availability."
