Hi Brian
Thanks! I had read that. But I had also done an animation of images from sol 19 to sol 24 which suggested that it was possible that the interesting fragment (thingie) might not have been totally destroyed but further fragmented to form the pices that NASA used to proclaim sublimation of ice when they disappeared two days later.
see gif animation below

It is most likely true that the thingie was wantonly destroyed but there is a slim possibility that it was further broken into the pieces seen in the left trench shadow of sol 20. There were no shadows in that area on sol 19.
If I remeber correctly Horton was the first to peer into the shadows and suggest that the thingie had been broken into further pieces that could be seen in the shadows. Not to suggest that he is right but there may be other interpretations of the images.
In any case, My main point is that there is another possible "thingie" and I think that they should study it to the extent possible, at least to see if it sublimates and how long it takes to sublimate.
