Lakes such as Lake Magadi of Kenya and Lake Natron in Tanzania are so saturated with salts that they form almost solid deposits of encrusted white soda.
Sellised järved nagu Magadi järv Keenias ja Natroni järv Tansaanias on nii suure soolsusega, et sinna on moodustunud peaaegu tahked soodalasundid.
