`I grew up in the Ozarks and my grandparents were from Ozark, Arkansas, a place I have visited often.  I've never heard that Ozark stood for ``toward Arkansas`` and believe this is incorrect.  In the case of Ozark, Arkansas, at least, the ``aux arc`` referred to the ``bend`` or ``bow`` in the river that the town was formed around.  With respect to the general region, I suspect that the the term may have referred to the shape of the hills themselves, that is, ``in/at/among the arcs (hills)``.  `
