Geologic Formations. The geography of the present Niobrara River valley is closely tied to the Sandhills of Nebraska. Geologists estimate that deposition began about 98 million years ago, when marine seas once covered the area. The seas were followed by alluvial stream deposits, and finally aeolian (windborne) deposits and volcanic periods.
