The Waimakariri Glacier.

This glacier in the height of the Great Glacier period obtained also a considerable size. It was at least 54 miles long, reaching as far as the middle portion of the Malvern Hills, where on the western page 392slopes of Abner's Head large morainic accumulations have been preserved. There is also ample evidence to show that during its greatest extension the Rakaia and Waimakariri glaciers joined by the pass, on the summit of which Lake Lyndon is now situated. In the Historical Notes of the survey I have already alluded to some of the characteristic features, as showing such abundant signs of the effects produced by the enormous glaciers of the district, so that I need not dwell further upon it.
