I am trying to learn about sulfur caves, particularly in the
Philippines. Do they exist (I presume they do in volcano country) and
what are their locations? Can you recommend sources? Many thanks.

Dear Joseph,
I searched a database called GeoRef for caves and Philippines. It only
had three matches and they were about guano not sulfur. I descended into
the labyrinths of the web seeking homepages on caves in the Philippines.
I found some interesting stuff but nothing to help you. With all those
volcanoes there must be some lava tubes (and caves). Looks wide open.
Let us know what you find.
