Rock study, Moonstone Beach, Cambria
Sea-sculptured outcrop of Cambria-slab graywacke sandstone, which is typically massive and largely featureless. Not here! Bedding planes are outlined by various shades of FeOX (and MnOX?) staining (+ heavy mineral accumulations?), and there are some cross-cutting (and later) iron-stained fractures as well. Scale may be judged by the green jadeite pebble at lower left that's maybe 3/4 in. across. You can see other green pebbles in this coarse sand, and there are always "pebble pups" sifting out their favorites from the never-ending and ceaselessly-replenished supply of attractive rounded pebbles. When you live here, you can fill your lifetime needs for pretty pebbles in a month or two -- but I still stick unusually pretty ones in my shirt pocket every week or two. Lots of room in the yard for rejects!
