Thank you Bill.
I was wondering, since I haven't heard about caves in that area either.
I just checked the geologic map of Mexico and right at Artega,
Michoacan, it's all granite, but there appears to be some limestone
relatively close, maybe it's there that the caves are.
And maybe because
No, Logan, AMCS (or at least I) doesn't know anything about caves near
Arteaga, Michoacán. The caves we know about in Michoacán are farther
north, near the Colima border. It is now possible for anyone to search
for most AMCS information on the web:
