I think you'll be surprised, then.

Domes don't appear in craters as small as this, unless you're near the polecaps and encounter the vagaries of polar layered deposits which DO mound within craters.

Despite me publishing a genuine attempt to correlate "White Rock" as a diapiric dome - of ice, not salt [ !! ], I no longer believe this. I think the White Rock is a sulphate deposit akin to the Meridiani feature, but perhaps less iron-rich and so lacking haematite.

I now think that many of the so-called resurgent domes are in fact fossilised hot springs in craters that built up in volcanic fashion as layers and draped sheets of evaporites.

Anyway, there's no point arguing about what we're about to see revealed. We've each posted our guess, and we'll see who is closest.

As usual, we'll all be wrong, this being Mars! :-)
