The most merciful thing in the world, I think, is the inability of the human mind to correlate all its contents. We live on a placid island of ignorance in the midst of black seas of infinity, and it was not meant that we should voyage far. --- H.P.L.

This geocache is going to be a difficult one and extra-special preparation should be taken in its execution.

If the stars are right, the above-stated coordinates will lead you to a coastline of mingled mud, ooze, and weedy Cyclopean masonry which can be nothing less than the tangible substance of earth's supreme terror. Take a moment to awe at the unbelievable size of the greenish stone blocks, at the dizzying height of the great carven monolith, and at the stupefying identity of the colossal statues and bas-reliefs.

However, if you come at the wrong time, you will need a bathysphere.

The polarising miasma welling out from this sea-soaked perversion will degrade your GPS signal as you near the monstrous Acropolis. Also, the geometry of this place is abnormal, non-Euclidean, and loathsomely redolent of spheres and dimensions apart from ours. Watch your step. Waypoint often.

The cache is a standard ammo can located in an an angle of masonry which is acute, but behaves as if it were obtuse.

    I traveled all this way and all I found was empty ocean. I guess the stars just weren't right. I forgot to bring my bathysphere. I was really looking forward to snagging that autographed copy of the Pokethulhu RPG.

    It was quite a climb up the montain of mingled mud, ooze, and weedy Cyclopean masonry but I didn't find any inhabitants and certainly wasn't chased by any grumpy landowners. What a dump. Maybe a good rain would wash away all the foul smelling slime.

    I took the jigsaw puzzle and left a golf ball I had found next to a large crater that had at first seemed like a hill. And when I got home, it turns out that none of the puzzle pieces actually fit together to form a picture. You can lay them out and sort-of see a landscape but fitting the pieces together ruins the effect. What a junky item to leave in a cache.

    After logging a few caches during our vacation in Chile, we chartered a boat in Valparaiso. The sailors running things were hesitant to take us where we wanted to go but when we told them that the fishing was excellent and threw more money at them, their reluctance disappeared.

    The weather started getting rough and the tiny ship was tossed. (Ha ha). The weather was a bit heavy for a while but wasn't that bad. Afterwards, we had the strange sensation of 'rolling downhill' towards the island which was exactly as described. Awful, slimy beaches and even without a cloud in the sky, the noon-day sun seemed dim. Worse than Atlantic City. If we weren't trying to log a 5/5 cache I wouldn't want to spend my vacation here.

    James is useless if the GPS doesn't have signal so that left me to search in earnest while he puttered around the megaliths. I found it after about 45 minutes of searching. Signed the log. Took the Elder Sign neclace and left a GeoHack gaming card. I was just closing the cache when there was an awful slavering and gibbering. James came running past and, knowing that he usually runs for good reason, I ran too.

    We plunged frenziedly over endless vistas of green-crusted rock, pursued by a mountain that walked or stumbled, an eldritch contradiction of all matter, force, and cosmic order. We would surely have been overtaken had it not, at the last moment, fallen backwards. Perhaps it was tripped by the same phantasmally variable geometry that had confounded us.

    We got to the boat and made best speed for Chile. Since the rest of the crew was left behind (James said they were eaten), I suppose we won't be able to get our deposit back. And the fishing stunk, too.

    Some days ago, a delusional patient was brought into our facility, mombeling gibberish interspersed with the occasional word and about having "Found it." Once he was properly sedated we were able to pry the electronic device from his rigor-like clenched fingers and determine that he seems to have found something placed by one of your so-called geocachers.

    When he awoke, he screached incessantly until we returned the GPSr to his posession. Only then, with him worshipfully holding the device like some sort of mystic talisman, were we able to piece together what it was he had found. What little I have been able to glean from his rantings has given me nightmares.

    Since the site is very careful do disavow any responsibility for what happens to cachers in the course of their hunt there is no legal way that you can be held responsable for his psychotic condition. Nevertheless, I am going to recommend that this cache be archived if not actually deleted from the site. Obviously the difficulty is way to high for most geocachers.

    I was unable to find it either but not because of a lack of signal. I was surely very near the prize when I was driven off by Muggles.

    Apparently mean-spirited and and on some sort of psychadelic drugs, a group of about a dozen people, if one can use such a word for such a gross representation of human abnormality, came up amongs the stones. They set up camp near the base of an immense carved door with a squid-dragon bas-relief next to which I am sure the cache lay hidden. With animal fury and orgiastic license, they whipped themselves to daemoniac heights by howls and squawking ecstacies that tore and reverberated through the granite like pestilential tempests from the gulfs of hell.

    Since they seemed there for the duration I decided to abandon my search for the day.

    I wasn't able to find it. I arrived at the bleak landscape but walked around in circles for hours. The GPS just couldn't seem to get any sort of lock.

    First to find! Buwahahahahahaha. The Mad Arab had been first to find my Mountains of Madness cache and disparigingly told me that he could place a more challenging cache than that and that I couldn't be the first to find it.

    I tricked him, though. By slipping into his dreams, I learned his darkest secret and was able to beat those other geocachers who rely merely on the website. Ha! Slowpoke electrons!

    Just you wait, Abdul al-Hazred, if I can keep one step ahead of the Hounds, I will place a cache that will really make your head spin.

    There are more logs but some things man was not meant to know.
