Dropping Ice Down a Ninety Metre Borehole

Occurred on December 18, 2015 / Taylor Glacier, McMurdo Dry Valleys, Antarctica

Info from Licensor: "During a November 2015 to January 2016 deployment to Taylor Glacier, Antarctica on a research trip funded by the U.S. National Science Foundation and supported by the United States Antarctic Program. Our camp was fascinated by the sound of the ice scraping against the borehole wall, shattering into thousands of pieces and then slamming at once into the bottom of the 90 m-deep hole—sending reverberations back to the surface that likely would have caused hearing damage if you placed your ear directly above the hole. Over a challenging two-month season working on this cold, windy glacier, it was a favourite past-time to put a piece of ice down one of the holes to hear this incredibly satisfying sound.
