The Clutha Glacier.

Looking at the size and form of Lakes Wanaka and Hawea, both surrounded by morainic circumvallations of no mean size, and considering the physical features of the Clutha valley, ample evidence is offered to us that an enormous glacier, to the former termination of which my travels have not extended, must have descended by this valley. It is however evident that this glacier, one of the Largest in New Zealand, reached much beyond the mouth of the Lindis, and received a further accession by the Kawarau Valley from the Lake Wakatipu glacier, the main branch of which descended by the valley of the Mataura. The length of even that part of the Clutha glacier from its beginning at the head of the Lake Hawea valley to the junction of the Lindis is 68 miles. The immense morainic accumulations near the sea-coast, north of the mouth of the Taieri river (Otago), described by Professor Hutton in his "Report on the Geology of Otago," page 62, might be the frontal moraine of this glacier.
