In the late 1970s Austin Post was working for the US Geological Survey and predicted that Columbia Glacier would disintegrate and discharge icebergs into Prince William Sound, posing a threat to tankers carrying oil from Alaska’s north slope. He then obtained a surplus navy launch that he named the Growler, added a steel keel and constructed a cabin that slept six, organized a crew, and in 1977 set sail for Juneau and Columbia Glacier. The following is the story of the voyage and the impact it had on glaciology.
