On the limb of an anticline, near-vertically bedded turbidite sandstones in the Bude Formation (upper Carboniferous) display sedimentary structures which can be used to determine the 'way up' of the bedding. Here, the sandstones display small-scale slump or load structures on the basal surfaces, and some beds show 'fining up' on the grain size (indicated by gradual darkening of the bed).

These structures demonstrate that the vertical beds here get younger to the right.
