There's some superb images coming in of the stratification exposed on rocks in the Erebus highway... it looks like this place was worth a visit for itself (of course) and not just for sticky drift avoidance...

I should probably get excited about pictures of the sand and pebbles too but I can't seem to

attached is one such partial image posted 17-Sep

One thing I've noticed are the "rounded" paving stones, the latest seen in the right foreground below, and an earlier color image of one. Any ideas on what we're seeing here? This is a distinctive pattern: one was unusual, but two make a trend... My thoughts are that they might be shock-related from earlier, eroded-away craters. If anyone says "stromotolites" I'll throw a hissy-fit. --Bill -------------------- Dawn-- Ceres Pluto Encounter Rosetta Mission

Possibly with further evaporite formation on top of jumbled ejecta blocks. -the other Doug -------------------- “The trouble ain't that there is too many fools, but that the lightning ain't distributed right.” -Mark Twain
