Might as well TRY to keep this arbitrary schedule o' mine, I guess! Anyway, briefly, here are some pictures I snapped down in the Guads. No carbonates (yet), but here are some nice pictures of some recent gravelly/cobbley cross-bedding in a modern stream cut. Flow is to the left!
Notice the direction of cross-bedding in ABOVE the fieldbook in the second photo? Kinda goin' the wrong-direction, ain't it? I reckon I'd call that backset cross-stratification, maybe do to the impingment of upper-flow regime conditions on the flow.
