The red arkosic sandstones speak of a crystalline source nearby, subjected to subaerial weathering. The small festoon cross beds speak of rapid incision and channel filling. Altogether it looks like an alluvial fan at the base of mountains of crystalline rock.
And there they are in the background. Not the original mountains, of course (these rocks are a billion years old), but the crystalline basement that still records the orogeny.
