Today's Dawn photo:

A lot more little craters visible but still nothing
over ~20 mile. What seems to be an ancient 50-mile
crater has a fully illuminated vertical side, (not
sloped like a crater wall). Disdurbed terrain below
the 12-mile-high cliff makes it look like a "slump"
feature. IF Vesta is hard basalt rock, how could it
SLUMP? And the illuminated cliff-face is high albedo,
"burnout" white, like ICE. (A spot check shows the
actual pixel value is 180 out of 256 grays, a "30%"
gray, still dam bright for basalt.

On the (right) side most fully illuminated, apparent
"craters" with very dark bottoms and albedo rims of
no apparent height. Filled with dark lava? Flooded
craters as are seen on other bodies? Many "gouges"
revealed on the left, at lower sun-angles, are sinuous,
like rilles. More lava flows?. Why no recent-ish craters
bigger than 20 miles?

I love a mystery.
