The original edition of this publication consisted of a twenty-page bound booklet and eight large color photographs in an envelope, plus a very large, loose, folded map of the cave. This bulletin is largely superseded by Bulletin 10, Caves of the Golondrinas Area, but it is of historical interest, especially the photographs.
The PDF contains scans of all of these in one file. The text is searchable to the extent that Adobe Acrobat's OCR program was able to "read" the text successfully.
