Initial scouting and selection of safe sites for tunneling into Taylor Glacier.
This short film describes the initial scouting and selection of potential safe sites for tunneling into Taylor Glacier for the 2009 field season. The previous sampling tunnel from 2007 was found to be unsuitable for reuse during this recce and so it was necessary to find another site where it would be safe to excavate a new tunnel. This mainly involved inspecting the top and sides of the glacial margin for any fractures or crevices that could result in ice falling down onto the tunnel site later in the field season.
