Abstract:
The Rhone Glacier, Taylor Valley, Dry Valleys was observed and surveyed to determine the structural glaciology and movement of the glacier. A tunnel was excavated into the true right western face of the glacier, 100m up from the terminus and strain arrays and plumblines were installed. A 4m deep shaft was excavated, at the end of the tunnel, to the bed of the glacier and the ice was sampled for analysis including physical description, isotope analysis, oxygen content, solutes present, pH and debris concentration. The strain arrays and plumblines were re-surveyed two seasons later at which point all pegs and bolts were removed.
