I have a question for old-time El Abra (Mexico) cavers. Back in the 1970s, a deep pit was found near Tanchipa and called Sótano de Coatimundi (after the animal). Later (the next day?) another deep pit was found on the other side of the trail and called Sótano de Coatituesday (a great bilingual pun). The description of Coatimundi mentions a second vertical entrance, but it is never referred to as Coatituesday. As far as I know, there is no map of either cave.

So my question is, is Sótano de Coatituesday the second entrance to Coatimundi, or a different cave altogether? This is something Logan McNatt might have known. Neal Morris would probably also know, if anyone knows how to contact him.

Thanks for any information on these caves,
Mark Minton

Yes, Mark, there is a Sótano de Coatituesday about 120 m ENE of S. de Coatimundi. This is from the Oztotl Project database, 2024, courtesy 
of Peter Sprouse. I looked it up in QGIS.

I'll send you a screenshot of it separately.
