Ripply Sandstone

Sand grains transported by underwater currents can get arranged in bedforms such as ripples and dunes.  

Dr. Ronny Nalin, of the Geoscience Research Institute of the General Conference of Seventh-day Adventists, is investigating sandstone layers deposited subaqueously that extend laterally for tens of kilometers. Learn more about his work on processes of sediment transport and deposition and why it matters for a biblical perspective of earth history, through the links below.
