Pockmarks
Check out how deep the big one is at lower right. Uncharacteristic for a crater compared to its diameter.
Another interesting thing is that Wild 2 looks to be round compared to Halley and Borrelley's elongated shapes. The 70 photos to come could reveal a different looking comet and will surely keep the team busy for a couple years.
Have to give credit to LM for a well built craft.
