Beyond the Mountains of Madness

Watermarked PDF

An Epic Antarctic Campaign & Sourcebook

Little by little they rose grimly into the western sky; allowing us to witness the various bare, bleak, and blackened summits . . . in the reddish Antarctic lights against the provocative background of iridescent ice-dust clouds. In the whole spectacle there was a persistent, pervasive hint of stupendous secrecy and potential revelation. . . . I could not help feeling that they were evil things - mountains of madness whose farther slopes looked out over some accursed ultimate abyss.

—H. P. Lovecraft


The scientific world was amazed by reports from the 1931 Miskatonic University expedition into uncharted Antarctica. The entire world was shocked by the tragedy which followed. Now a new larger expedition will brave the mysteries of the icy continent. How credible were Miskatonic University reports of fossilized remains of ancient life forms predating all known terrestrial life? Will your expedition return in glory or tragedy? 

This massive book includes considerable source material on the Frozen Continent, the equipment of the time, and even expedition planning. This is a roleplaying sequel to Lovecraft's classic tale, "At the Mountains of Madness", of unimaginable scale. Over 400 pages of pure adventure!

There will be any update with an index planned?
That is almost mandatory for this massive book

Are there any plans to make this available in print? This one is incredibly difficult / expensive to get on the used market.

Thanks for the suggestion, but I already came to the same conclusion. :-) It wasn't too expensive to get a hard cover on Lulu - certainly cheaper than buying the real deal.

Original electronic
Scanned image
These products were created by scanning an original printed edition. Most older books are in scanned image format because original digital layout files never existed or were no longer available from the publisher.

For PDF download editions, each page has been run through Optical Character Recognition (OCR) software to attempt to decipher the printed text. The result of this OCR process is placed invisibly behind the picture of each scanned page, to allow for text searching. However, any text in a given book set on a graphical background or in handwritten fonts would most likely not be picked up by the OCR software, and is therefore not searchable. Also, a few larger books may be resampled to fit into the system, and may not have this searchable text background.

For printed books, we have performed high-resolution scans of an original hardcopy of the book. We essentially digitally re-master the book. Unfortunately, the resulting quality of these books is not as high. It's the problem of making a copy of a copy. The text is fine for reading, but illustration work starts to run dark, pixellating and/or losing shades of grey. Moiré patterns may develop in photos. We mark clearly which print titles come from scanned image books so that you can make an informed purchase decision about the quality of what you will receive.
Original electronic format
These ebooks were created from the original electronic layout files, and therefore are fully text searchable. Also, their file size tends to be smaller than scanned image books. Most newer books are in the original electronic format. Both download and print editions of such books should be high quality.
