A flat tire. Opportunity for an extended walk.
We’re merely a hundred yards on the track and already in the middle of an inspiring discussion about the assets and drawbacks of polygamy as encouraged by the Islamic belief. My attention in the admittedly interesting subject dies abruptly when I notice a chunk of dark rock passing the corner of my eye. “Halt!” Getting off the vehicle, I notice more dark debris in a wider perimeter. Probably we’ve run over another shattered fireplace of Neolithic origin.
Wondering about the pseudo-meteoritic appearance these specific rocks display, we’ve come to the conclusion that once the magnesium in the dolomite has become oxidized by fire, its surface is vulnerable to the effects of desert varnish. Within a few centuries such stones are coated black. But unlike the other prehistoric campfires we came across, this particular one completely lacks the usual flintstone scrapers and petrified bones.
