Is the patron interested specifically in the approximately circular area
(diam. ~ 125m) at the western end of Balan Sokak that is of apparently
lower elevation than the surrounding surfaces? I am not a geologist, but
both that area and similar but smaller areas about 1250m to the
southwest look as if they might be sinkholes, in which the subsidence
was the result of subterranean rather than surface erosion.

Hi Jeff:
I can't confirm it without knowing the geology of the area, but it looks
more like differential erosion has exposed an uplifted but un-deformed
sedimentary rock sequence with nearly horizontal or slightly dipping
bedding.

A patron here is very interested in a geologic feature in Turkey,
visible at http://binged.it/17SCnzL or http://goo.gl/maps/UplsF
I suspect that it's a volcanic caldera, but can anyone confirm?
Thanks!
