Rock

Feeling rocked by the image doldrums? Roll on over to our 'Rock' category—a geologically fabulous gallery featuring everything from pebbles that peacock around on riverbeds, to mountains that believe in life after erosion. Whether you need a sediment snapshot for your geology-guru friend or an epic crag for that motivational “climb every mountain” post, we've got rocks polished to picture-perfection. Here, sediment booty calls, and every shale has a tale. #particleswithpersonality
