Hi Richard,

I thought of this immediately when I looked at the first pictures. Then I
imagined one of the larger hits knocked it away from what ever it was
rolling around.
And, then I thought Vesta trying to stretch itself and the feature is a
result of that!
Who knows!!! It will be interesting to learn. Watching this closely.

Kind Regards,

Jim Wooddell
