Three ice rises appear here as long parallel lines near the edge of the West Antarctic Ice Sheet. Ice rises are rounded elevations that form where the ice shelf touches areas in the seabed that are elevated, but nevertheless below sea level.

The ice shelf flows over these higher parts of the seabed and completely covers them with ice. The ice rises formed in this manner are typically 100 to 200 meters high.
