The Trench Glacier is a deeply jagged glacier on the east side of Alexander I Island . It is 10 km long, 3 km wide and flows in an easterly direction to George VI Sound , which it reaches immediately south of Mount Athelstan .
The US polar explorer Lincoln Ellsworth photographed the mouth of the glacier during his transantarctic flight on November 23, 1935. The US cartographer WLG Joerg used these aerial photographs for an initial mapping. The Falkland Islands Dependencies Survey carried out measurements of the glacier in 1948 and 1949 and gave it a descriptive name ( English trench = German incision, ditch )
