Distinguishing Features :
Remarks : Note that there is no established WMO symbol to depict Keel/Bummock. It is recommended that the WMO symbol for Ridges/Hummocks be inverted, so the straight line representing the water surface is at the top - and used for Keels/Bummocks. This discrepancy can be corrected in a future revised edition of the referenced WMO documents.
