The Raak Plains Salinity Province is located around the specific primary salinity feature of the Raak Plains Salinas. Saline groundwater discharge from the deeper regional scale Groundwater Flow System (GFS) has salinised a clay depositional feature called the Blanchetown Clay, which has then been blown away by the wind to form saline depressions known as "boinkas". |
