A bridge or span of some kind?

{Ed. NW of Endymion same width as crater}

Golf ball crater anyone?
Just like the one on mars.
Hmm..:puz: Is this what you were
talking about?

Ed. NW of Bridge same distance again. Note the little spheres in the left side of the crater

L-LO2 Just a tiny fore warner of
the big storm? Or a column of
smoke...

R-LO1 The same cloud, but
taken a little later... We see
more dispersal, but the image is
still there...
