An interpretation
of the O'Brien Springs
Sandstone tide-dominated
deltas of Setting 1 in the
Hanna Basin area of southern
Wyoming (From Uroza
2008
) . Paleocurrent patterns
(see northerly set of lobes)
suggest that the shorelines
initially prograded east and
southeastwards and were of
mixed wave-tidal energy, but
were then defl ected
southwards by southerly
directed seaway tidal
currents. Lettered locations
on southern lobes are from
Mellere and Steel (
1995b
)

Late Pleistocene
(
lowstand
) Yangtze-Yellow
River delta and modern
Yangtze delta, both of which
are tide dominated (Hori
et al.
2002
) and have an
orientation refl ecting
southward-directed,
wave-driven longshore
currents and Coriolis-
defl ected tidal currents (Chen
et al.
2000
) (Diagram

good analog for the WIS
distal shorelines by Hampson
et al.
