First (1980): Dark blue cover, Jeff Dee artwork.  ISBN on back cover bottom left.  "A Wilderness Adventure for Character Levels 3-7" is printed on two lines, top of the front cover.  "All Rights Reserved" is the last line of text on the front cover (repeating itself).  This was the first full-color-covered module produced by TSR, and was included in the First print of the D&D Expert Set (it was also sold separately, i.e. shrinkwrapped, and is considerably rarer in that condition).  Note:  On all copies we have spotted, the module booklet is copyright 1981, and has a "9034" module code in the lower right (9034 is assigned to B2 Keep on the Borderlands).  The cover, however, shows the correct copyright (1980) and code (9043).

Second (1981):  Dark blue cover (though a lighter-toned cover is also fairly common), Jeff Dee artwork.  On the lighter-toned copies, only the ISBN is on back cover bottom left; the darker-toned copies have both ISBN and Product Number on the back left.  "A Wilderness Adventure for Character Levels 3-7" is printed on one line, top of the front cover.  The repeated "All Rights Reserved" (see above) has been removed.  This print came bundled with the Second print of the D&D Expert Set, and was also sold separately.  The discrepancy mentioned above ("9034" code, 1981 copyright) is sometimes present with this print as well. Thanks to Dave Aho, Matthew Foster, Curt Gould, Dan Harshman, John Justice, and Luca Lettieri for this info, and to Dave Aho for the scan of the lighter-toned version.

Third:  Dark blue cover, Jeff Dee artwork.  ISBN and Product Number on back cover bottom left.  "A Wilderness Adventure for Character Levels 3-7" is printed on one line, top of the front cover.  This print came bundled with the Third print of the D&D Expert Set, and was also sold separately.

Fourth (1983):  Red cover, Tim Truman artwork.  It was bundled with the Fourth and Fifth prints of the Expert Set.  Front cover layout is completely rearranged, in line with the current TSR module style.  Several monsters have been changed/excised, to conform with what monsters are available in the Basic and Expert sets (for instance, the three sharks in the temple were changed to crocodiles).  Also, there is a glaring error on the maps, specifically the outtake diagram next to the map of the first floor of the temple.  The diagram is a sketch, showing how an arched passage leads under the face set in the middle of the wall of the main chamber.  This printing lacks the sketch (present in the first three printings above).  As a consequence, it appears that the dungeon chambers are completely inaccessible! Thanks to Brett Altschul for this info.
