At the end of March 2006, another iceberg coming from the Ross Ice Shelf, named C-16, hit the ice tongue, breaking off another large piece (more than 100 square kilometres or 39 square miles). Both of these incidents

The
Drygalski Ice Tongue is thought to be at least 4,000 years old. The recent history of the combined glacier and ice tongue used analysis of rocks deposited along the margin of the David Glacier to identify a rapid thinning event initiated over 7,000 years ago that endured for ~ 2,000 years.
