We are trying to obtain as much information re. the above volcanic structure
in Yemen and wondered if you knew of an expert who may have investigated
Have you done any work connected to the incense road?

Delighted to hear from anyone interested in ancient cultures and volcanic
caves! Will pass on your message to people who may know about studies of
the volcanic structure of Yemen.
Don't know if you have looked over our website. If so, you may notice that
in the last 3 years we investigated just a few volcanic areas in Saudi
Arabia and found neolithic throwing sticks, remains of ancient walls, etc
etc inside lava tubes. As there are 89,000 sq kms of lava fields in Saudi
Arabia, it seems likely that we have barely scratched the surface and that
all sorts of archeological wonders are to be found. The lava tubes have a
perfect environment for preserving whatever ends up inside them.... so, for
example, the scat of hyenas and wolves is perfectly preserved, and inside
them we find plant material, pollen, etc. that furnish all sorts of info on
ancient climates, flora and fauna.
We haven't studied the incense trails as such, but as they skirt several of
the big harrats in Saudi Arabia, it seems quite likely that the lava tubes
in these harrats may contain evidence of their passing.
So far no archeologists have set foot in the caves we have discovered, but
we hope that someday great discoveries will be made in the lava caves of
