The DC Grotto Library has a collection of National Geographic magazines from 1934 through 1997 that contain cave-related articles.
The good news is that there is an index to the articles. It was produced by a caver in Australia, Glenn Baddeley, who created the index and posted it on his website. A reformatted version of Glenn’s index is included below (with his permission). (Sadly, Glenn Baddeley’s site is no longer operational).
The following index shows the article titles, Glenn Baddeley’s comments about the articles, and the date of the issue containing them. Only the issues in the Grotto Library are included.
