It is utterly unspectacular.

Yes, the geological wonder known as the Guelb er Richat – three days traverse into the Sahara – is no more than melted ice cream at eye-level. From above its concentric rings dazzle the mind, alien in appearance, yet strange in perfection.

But potsherds strewn across dirty hills are less jaw-dropping than head-scratching.

O, how perspective floats unwittingly!
