''At the Mountains of Madness'' is a 1936 novella by Creator/HPLovecraft, serialized in ''Astounding Stories'' magazine. It revolves around the geologist William Dyer, leader of an expedition to Antarctica. While digging for ice cores, his team uncovers the frozen bodies of creatures of indeterminate origin; later, most of the expedition is mysteriously slaughtered. Dyer's party discovers the ruined camp, and he and a graduate student fly over the mountains into mystery to investigate further. They soon find themselves beyond massive mountain peaks, in the ancient ruins of a colossal city, completely alien in design...

A film adaptation, directed by Creator/GuillermoDelToro and produced by Creator/JamesCameron, [[http://www.slashfilm.com/2010/07/28/guillermo-del-toro-to-direct-at-the-mountains-of-madness-with-james-cameron-producing/ was in the works,]] but [[http://uk.movies.yahoo.com/10032011/5/studio-axes-tom-cruise-film-0.htmlv was cancelled after the failure of the Wolfman reboot.]] However there has recently been talk about revisiting the project.

Has been adapted twice as a radio drama, first by the Atlanta Radio Theater Company and later by the H.P. Lovecraft Historical Society for their ''Dark Adventure Radio Theater'' series. A ComicBookAdaptation was also done by I.N.J. Culbard.

!!This novella provides examples of:

* AcquittedTooLate: Gedney.
* AIIsACrapshoot: The example provided by the Shoggoth almost fits this trope to a T, though the Elder Things didn't intend for them to be intelligent ''or'' adapt to live on land where they would be almost impossible to control.
* AlienBlood: The blood of the Elder Things.
* AlienGeometries: As expected for Lovecraft, the expedition nearly gets lost thanks to the nature of what they have discovered. In this case it's at least as much the alien architecture as any twisting of space.
* AncientAstronauts: The Elder Things and their slave servants, the Shoggoths.
* ApocalypticLog: The story, and there is one implied written by the alien Elder Things which no-one in the expedition can read, but is accompanied by various wall carvings depicting images which convey the history of the race and its decline.
* ArtisticLicenseBiology: Giant penguins? Theoretically possible. ''Blind'' giant penguins? Not at all likely, considering penguins are almost entirely sight-hunters. It's implied to be some sort of corruption effect, though, rather than straight evolution.
* BadassNormal: An odd example, but the Elder Ones certainly fit. ''All of them''. Although not human by any means, they were carbon based lifeforms, that, without any supernatural powers or anything similar, led a war against Star Spawn and their god/priest Cthulhu and fought them to a standstill. They ''literally'' [[DidYouJustPunchOutCthulhu punched out Cthulhu]]. And all this while also holding off attacks from the Mi-Go.
* BatmanCanBreatheInSpace: The Elder Things traveled to Earth naked using their wings as living solar sails.
* BizarreAlienBiology: The Old Ones apparently had gills, lungs, tentacles, wings, and numerous mouths, among other things. They seem to reproduce asexually and have massive, if not indefinite, lifespans, in addition to massively resistant bodies and nigh-impossible endurance (since they survived having been frozen for ''aeons'').
** Note that, as far as Lovecraftian beasts go, they're stated to be a species of {{Badass Normal}}s, since despite their biological superiority to humans, they made little or no use of magic (unlike the Deep Ones), were constrained by time (unlike the Race of Yith) and had bodies made of "regular" matter (while the Mi-Go and Star Spawn of Cthulhu were explicitly stated to be more ''exotic'').
* BizarreAlienLocomotion: Flying through space with wings is apparently fine and dandy if you're an Elder Thing. They were supposedly flapping the luminiferous Ether, but science has marched on.
* BlobMonster: The Shoggoths.
* ComicBookAdaptation: Done by I.N.J. Culbard, with an art style and character designs invoking ''{{Tintin}}'', weirdly enough.
* CoolPlane: '''The''' reason for which the expedition penetrates so far in the Antarctic.
** Usually identified by modern fans with the [[http://en.wikipedia.org/wiki/Dornier_Wal Dornier Wal]] / [[http://en.wikipedia.org/wiki/Dornier_Do_R Super Wal]] planes of [[TheRoaringTwenties the mid-1920s]], due to the fact [[RealLifeWritesThePlot they were used by Roald Amundsen over the Arctic in 1925]]. None of them however could raise to 24,000ft to cross the mountains, so they might have been [[http://propnomicon.blogspot.com/2011/11/wings-over-antarctica-part-deux.html Dornier Merkur]] type instead.
* DoingInTheWizard: Many elements of previous stories in the Franchise/CthulhuMythos are recast as being of extraterrestrial, as opposed to supernatural, origin. [[AlternateCharacterInterpretation Another interpretation]] is that the protagonist of the story was a scientist, and the Old Ones seem very science-based themselves. It could just be a case of the protagonist, the old ones, or both trying to explain where the creatures of the Franchise/CthulhuMythos came from. With science.
* DownerEnding: Lake's entire party is killed by Elder Things. On top of that, Danforth has probably gone insane, and Dyer is trying to stop a second arctic expedition from taking place, and chances are no one will believe the reason why. But hey, it's Lovecraft, what did you expect?
* EverythingsBetterWithPenguins: Subverted. How do six-feet-tall, blind, absolutely white penguins sound?
** Regular penguins are also described as ugly abominations.
* EvilDetectingDog: Though "evil" isn't really the right term.
* EvilSmellsBad: As it is wont to do in a Lovecraft story. Ironically, its stated that while the Elder Things odor isnt exactly pleasant, its miles better than the toxic vapour the Shoggoths excude.
* FramingDevice: Both audio drama versions are framed as radio news interviews with Professor Dyer.
* FunWithAcronyms: The news station that interviews Dyer in the ARTC radio version is known as W[[Franchise/CthulhuMythos CTH]] News.
* GoMadFromTheRevelation: [[spoiler:Danforth]] sees...''something'' past the far mountains. It's implied that he gets a good look at the [[spoiler: [[EldritchLocation dread city Kadath]]]] and through it sees a sight ''[[UpToEleven even worse]]''. Although never outright stated, from various gibberings, it's likely that [[spoiler: he got a good look at the history of many, ''many'' [[EldritchAbomination Eldritch Abominations]], including the Shoggoths, the Great Old Ones, and even Outer Gods like ''Yog-Sothoth'']].
* HarmlessFreezing: The Elder Things were frozen for a long period of time. When they're thawed out they go on a murderous rampage (understandably since several of them had been autopsied by the humans, possibly while still alive but not thawed enough to move.) The freezing and surviving is justified in that they are described as being extremely tough in comparison with humans.
** Dyer comes to respect and pity them once he realizes that they were sentient beings and scientists of their species in their own right, concluding that [[NotSoDifferent they did no differently to the human party than the humans had done to them]].
** WorthyOpponent:
--> '''Dyer''': ''"After all, they were not evil things of their kind. They were the men of another age and another order of being. Nature had played a hellish jest on them -- as it will on any others that human madness, callousness, or cruelty may hereafter dig up in that hideously dead or sleeping polar waste -- and this was their tragic homecoming. They had not been even savages -- for what indeed had they done? That awful awakening in the cold of an unknown epoch—perhaps an attack by the furry, frantically barking quadrupeds, and a dazed defense against them and the equally frantic white simians with the queer wrappings and paraphernalia ... poor Lake, poor Gedney... and poor Old Ones! Scientists to the last—what had they done that we would not have done in their place? God, what intelligence and persistence! What a facing of the incredible, just as those carven kinsmen and forbears had faced things only a little less incredible! Radiates, vegetables, monstrosities, star spawn — whatever they had been, they were men!"''
* HumanPopsicle: Very, ''very'' not human, but still the same idea.
* IndyEscape
* LateToTheTragedy: All of the dying happens before the viewpoint characters arrive.
* MadnessMantra: Tekeli-li!
** Also Danforth's listing off subway stations while running from the Shoggoth.
* MysteriousAntarctica
* [[ContinuityNod Mythos Nod]]: This story makes explicit references to many of Lovecraft's other narratives, and is one of the reasons why the Franchise/CthulhuMythos are thought of as a single, coherent universe.
* NothingIsScarier: The terrible vision that only Danforth saw, just before he and Dyer flee back to their plane, which pushed him over the edge into madness.
** Likewise, the very brief glimpse that Dyer and Danforth have of the shoggoth that pursues them. All Dyer can say is that it put them both in mind of a subway train roaring through a tunnel.
** Also notably, the narrator himself never sees the Elder Things alive and active, and there are no first-hand accounts of their actions in the story; only the consequences are visible, afterwards.
* NotSoDifferent: More or less explicitly stated of the Old Ones:
--> ''"Radiates, vegetables, monstrosities, star-spawn - whatever they had been, they were men!"''
** This is especially exceptional for Lovecraft's stories, where most things that are "different" are usually "wrong". The Elder Things are the most "human" and benign of the Mythos species. Aside from their strange biology and amazing toughness, they are made of mundane elements (compare with the Mi-go, or the partly-spectral flying polyps), they formed family units, and had an art-producing culture and an economy. Perhaps most importantly, they only lashed out at the human party in horror and vengeance for the ''humans'' mutilating ''them'' first, rather than out of sheer carelessness or malice.
* OffWithHisHead: The Shoggoths' main method of disposing of their hated masters is by crudely tearing off their heads through sheer force of suction.
* {{Panspermia}}: Of a sort: according to this story all life on Earth started with experiments the Old Ones let live out of apathy. So in other words, we're all the spawn of failed alien bioengineering.
* PurpleProse: Like everything by Lovecraft.
-->The leathery, undeteriorative, and almost indestructible quality was an inherent attribute of the thing’s form of organization, and pertained to some paleogean cycle of invertebrate evolution utterly beyond our powers of speculation.[[labelnote:Translation]]They were really freaking tough, and we will never understand exactly why.[[/labelnote]]
* ShoutOut:
** To Creator/EdgarAllanPoe's ''Literature/TheNarrativeOfArthurGordonPymOfNantucket''.
** The narrator refers to [[http://en.wikipedia.org/wiki/Nicholas_Roerich Nicholas Roerich's]] [[http://www.roerich.ee/galnew/gallery.php?l=eng&g=NR paintings of Himalayan landscapes]] when describing the mountains of the Antarctic.
** In the ARTC version the reporter who interviews Dyer is named Alice [[Creator/ClarkAshtonSmith Ashton]].
* SicklyGreenGlow: Shoggoths are described by Dyer as enormous black masses of protoplasmic bubbles covered in luminescent green eyes that are constantly forming, shifting around and dissolving.
* SlaveRace: The Shoggoths, to the Elder Things. Shoggoths were not originally created to be sentient: they were more like bioengineered construction equipment, and only became sentient through unintended mutations.
* StarfishAliens: The Elder Things are radially symmetric and built around pentagon and five-pointed star shapes. Shoggoths are just {{Blob Monster}}s.
* StarfishLanguage: The {{Trope Namer|s}}. The Elder Things communicate by making piping sounds through their breathing tubes.
* TimeAbyss
* TurnedAgainstTheirMasters: Originally mindless workers, the Shoggoths somehow evolved intelligence once the Elder Things relocated to Earth. It's hinted that it was a side effect of the Elder Things modifying them for their new world. A war was apparently fought to resubjugate the Shoggoths and keep them from wiping out their masters, and it seemingly worked... temporarily. After the Elder Things relocated to a giant, underground sea, it's implied that the Shoggoths once again rose up, and this time, they won.
* UltimateEvil: There's something even worse that the Elder Things or the Shoggoths at the mountains, never seen or even speculated of. It's implied to be what Danforth sees at the end of the story, driving him completely mad.
* UnreliableExpositor: Dyer considers the possibility that the Elder Things' histories may be colored somewhat. He wonders if the “exotic matter” of the Star-spawn and Mi-go is a mythological construct, and notes that there is no mention of the Great Race of Yith.
