Isopach map showing thickness of sands in the lower Cherry Canyon Fm.
Note channelized and
lobate forms of sand deposits and the presence of numerous entry points around the basin
margin. This is interpreted to indicate wide distribution of sands, primarily by eolian
process on shelves during lowstands, with subsequent influx of those sands through
numerous "lows" in shelf-margin carbonate deposits of the previous highstand.
