Interesting that there are Viking high resolution images of the Becquerel formation and they are almost the same resolution as the THEMIS IR images -- so they show almost the same thing.

And yes, the MOC references to the Becquerel "White Rock" (as well as the Trouvelot "White Rock" and quite a few other "White Rocks" -- as in Gale and Richardson and other craters) might well have been inspired by the efforts of amateurs to spot similar formations on Mars, based in turn by curiosity and speculation about the original White Rock in Pollack.

I think you put it very well here:

But we're doing what amateurs can do, by doing the grunt work of looking at thousands of images, and selecting those that are worth further research by the professionals. It's a wonderful thing that the Internet has made all this data available, and opened the doors for amateur planetologists to make a contribution to the field the way amateur astronomers have been vital to astronomy.
