Many other indicators are commonly present, including ones that can even tell you the angle of the depositional surface at the time ("geopetal structures"), "assuming" that gravity was "down" at the time, which isn't much of an assumption :-).In more complicated situations, like in a mountain belt, there are often faults, folds, and other structural complications that have deformed and "chopped up" the original stratigraphy.

For example, wave ripples have their pointed crests on the "up" side, and more rounded troughs on the "down" side.They are applied by geologists in the same sense that a "null hypothesis" is in statistics -- not necessarily correct, just testable.
