After the retaining ice walls melt away, stream deposits remain as long winding ridges.

All siliciclastic rocks are formed by inorganic processes, or deposited through some mechanical process, such as stream deposits (delta deposits) that are subsequently lithified.
These stones do not appear to be associated with stream deposits and are rarely more than fist-sized, which is consistent with the idea that they are gastroliths.
The "binary structure" of the sedimentary rhythms strongly indicates meandering stream deposits rather than braided river deposits as previously thought.
They can also form in terrestrial stream deposits.
During times when the seas retreated, stream deposits and dune sands were deposited or older layers were removed by erosion.
It consists of sandy, shallow-marine deposits with intermittent mud flat sediments, and occasional stream deposits.
It is most common in stream deposits (consisting of sand and gravel), tidal areas, and in aeolian dunes.
The region's geology developed from stream deposits from the erosion of the Rocky Mountains.
