Our scatteredpaleocurrentwork has provided evidence for episodes of flow to most directions of the compass.
From theCambridge English Corpus
In tidal areas, which have bidirectional flow, structures are formed with alternating layers of cross-beds dipping in opposite directions that reflect the alternatingpaleocurrent.
