Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. An exhumed river channel is a ridge of sandstone that remains when the softer flood plain mudstone is eroded away. The process begins with the deposition of sand within a river channel and mud on the adjacent floodplain. Eventually the channel is abandoned and over time becomes buried by flood deposits from other channels. Because the sand is porous groundwater flows more easily through the sand than through the mud of the floodplain deposits.
