Curiosity is peering closely at some Martian rocks...

Curiosity is peering closely at some Martian rocks...  The very same rocks I posted about a few weeks ago, showing them in the distance.  Now Curiosity has focused its hand-lens imaging camera at them.  In the image at right (click to embiggen) you can see the gray matrix, some reddish layers, and what appears to be tiny quartz pebbles.  To my eye it looks like layered sandstone peppered with very fine gravel.  That strongly implies the past presence of water: running water or ocean shore...
