Enlarged Views of 2002 Russell Fiord Closure and Russell Lake Outburst

These photographs show an enlarged eastward-looking view of a small section of the Hubbard Glacier terminus and the evolution of the "squeeze-push" moraine in front of Gilbert Point that blocked the tidal exchange between Disenchantment Bay (bottom of photos) and Russell Fiord (top of photos), creating Russell Lake which rose to 18.6 meters (61 feet) above sea level over 2½ months before it finally outburst on August 14, 2002 creating the second largest glacial lake outburst worldwide in historical times.
